February 23, 2016 INTEGRAL upper limits on gamma-ray emission associated with the gravitational wave event GW150914
Recent direct detection of gravitational waves opens a new window to space with the help of gravitational wave astronomy. Can other more developed branches of astronomy tell us more about the source of gravitational waves GW150914? See recent paper of one of our participants, Volodymyr Savchenko, with his colleagues which sheds more light on this question. http://arxiv.org/abs/1602.04180

June 12, 2012 On-line seminar of Fedor Bezrukov next Tuesday.
We have a pleasure to announce the on-line seminar of Dr. Fedor Bezrukov, one of the members of our common SCOPES project. The title of the seminar is "Standard Model and the Higgs mass - what can be learned about Standard Model?". The seminar will be on-line (because he is in Switzerland right now) through EVO translation. It starts next Tuesday, at 11:00 a.m. Kiev time. Video recording of the seminar is available here.
June 01, 2012 Summer practice for students "Introduction to Standard Model of particle physics" is starting next Monday.
This practice is devoted for students of Department of Quantum Field Theory (as well as interested students from Nuclear Phycis Department) of Physical Faculty of Kyiv Taras Shevchenko National University and holds yearly (sin 2009) under general supervision of Dr. Alexey Boyarsky, one of VIRGO coordinators. This year, the local organizer of the practice is Artem Ivashko.
First lecture is hold on Monday, June 4, in room 347 (VIRGO-class) of Bogolyubov Institute for Theoretical Physics, at 11.00. Place and time of next classes will be specified further.
The aim of the practice is to study Standard Model of particle physics (SM) drawing special attention to problems of science since formulation of quantum mechanics and special relativity. We will show how, by requiring complete (including all known processes), consistent (having no internal contradictions) and closed (all predicted particles are discovered) description of fundamental components of matter scientists have assumed existence of new particles and have raised the energies of accelerators to find assumed particles. We will demontrate that this process has closed with definition of SM, with the only missing component -- Higgs boson, with some hints on its existence found in LHC at 2011 and stated that in 2012 LHC either discover or exclude this particle. Our goal is not in a deep systematic study of all questions necessary to work in a wide field of particle physics in SM and beyond, but rather obtaining the overall picture and understanding of its processes. Therefore, during this practice we proceed with detailed study of some theoretical aspects necessary to understanding of key aspects of the theory, including those not covered by standard QFT courses; some historical questions; experimental search for theoretical predictions. The study will be organized not only in lectures but also in common discussions (with the prepaer speaker for each topic), as well as solving problems. To reach these goals we need full concentration and lots of self-sufficient work during 10 working days (2 weeks by 5 working days each) of pure time.
Prerequisites: relativistic quantum mechanics, introduction to quantum field theory (at the level of spring intensive).
Questions to study during the practice:
1. Problems with high-energy unitarity in Fermi theory, adding massive vector bosons as solutions of these problems.
2. New problems with unitarity in theory with massive vector bosons, adding new particles and reqiurement of Yang-Mills symmetry from unitarity conditions.
3. Problems with description of massive gauge theories, solving them with Higgs mechanism of spontaneous symmetry breaking.
4. Theory of strong interactions and its connection with theory of electroweak interactions. General structure of SM.
5. Observational tests of SM including prospects of Higgs boson detection at LHC.

June 15, 2011 Summer practice "Introduction to Standard model of particle physics".
During June 27 - July 6, we will hold the yearly summer practice for students "Introduction to Standard model of particle physics" in r.347 (VIRGO-class) of Bogolyubov Institute for Theoretical Physics. The aim of this practice is to study Standard Model of particle physics (SM), by emphasizing the problems of fundamental physics since foundation of quantum mechanics and special relativity. We will study how the requirement of complete (containting all existing processes), closed (all key assumtions and predictions have been verified) and consistent (not having internal contradictions) description of fudamental components scientists should have been assumed the existence of new particles and increase the energy of accelerators to test these assumptions. We will demonstrate that this process becomes closed in frames of SM having the only missing component (Higgs boson) which parameters are restricted from all sides. Therefore, LHC is the ultimate experiment to verify the SM -- it cannot miss the Higgs boson if SM is correct. We explain however most of scientist expects, even though SM is correct and Higgs boson will be found чому, there also exists a new physics beyond the SM which will be tested in part with the help of LHC and for testing the other part the completely different experimental methods will be needed. The aim of the course is not in a deep and systematic study of all matherial needed to work in wide range of particle physics in SM and beyond, but rather demonstration of general picture and understanding the nature of the processes which take place in SM, as well as help of young scientists in further choose of their scientific topics. Thereofore, this course will be additional to standard quantum field theory courses. It will combine the detailed study of some theoretical aspects necessary to understanding the SM processes including those not usually centered in standard field theory courses, phenomenology (information about observed particles and phenomena, their properties and corresponding experiments), some historical questions. The study will mostly take place in form of joint discussions (with a trained speaker for each task), and problem solution.
Prerequisites: relativistic quantum mechanics (Clein-Gordon and Dirac equations, including the case of external field). Between the seminars, food and drinks will be served. Everyone is welcome. The program of practice seminars is in VIRGO seminar webpage. The conspect of seminars can also be found here. Final list of problems is located here.

April 07, 2011 X-ray and gamma-ray data analysis - much faster with Ukranian National GRID!
One of the most important needs for our Observatory is the need for computing resources. Many highest-ranked scientific problems related to X-ray and gamma-ray data analysis usually need hundreds or even thousands of CPU-hours almost unreachable using single machines. To solve this problem, VIRGO provides the computing infrastructure of its computing classes, about 20 CPUs in total. However, during this year situation will improve drastically, as our project "Development of GRID Virtual Organization virgo_ua", selected for funding for 2011 year, will include the implementation of data analysis of XMM-Newton, Chandra and Fermi observatories covering most of current VIRGO scientific activites.
Importantly, because the abovementioned data analysis can be simply splitted on computing tasks runned independently on a single CPU, the best choice for such a data analysis is to use different computing clusters, rather than a signle supercomputer. Therefore, such tasks can use the existing infrastructure of Ukranian National GRID, currently containing more than 2000 CPUs for more than 20 computing clusters, in the most effective way.
The planned amount of funding for this project (project leader -- Yuri Shtanov, participants -- Alexey Boyarsky, Dmytro Iakubovskyi, Denis Malyshev, Denys Savchenko and Igor Zinchenko) during 2011 year is 80.000 UAH which is enough to develop the handy grid-working infrastructure for astrophysical database. Therefore, we plan that most of active VIRGO participants will have access to huge computing power of Ukranian National GRID which will further enhance quality and quantity of our scientific projects.

October 08, 2010 VIRGO proposals for XMM-Newton AO-10.
The tenth Announcement of Opportunity (AO-10) for XMM-Newton X-ray cosmic observatory, launched in 1999 by European Space Agency (ESA), has been closed today. As XMM-Newton is one of the most popular satellites used by X-ray community, VIRGO members has been largely participating in preparing and submitting scientific proposals for AO-10.
The details on AO-10 can be found in XMM-Newton webpage. Note that the participation in AO-10 allows Ukrainian astronomers and astrophysicists the unique opportunity to ask for XMM-Newton observing time looking for their favorable objects (as Ukraine is not a part of ESA) and thus allowing the world-class scientific research in VIRGO-like computing facilities without significant money investments. In fact, 1 second of XMM-Newton observations costs ESA about 10 Euros! If these proposals have been approved to XMM-Newton Observation Time Allocation Committee, the following groups will be the owners of their data prior to 1 year after the observation, after that the observation will become available to broad scientific community.
The details of submitted proposals are listed below:
1) Probing the nature of dark matter particles with XMM-Newton (A. Boyarsky, O. Ruchayskiy, D.Iakubovskyi, D. Malyshev, T. Maccarone and M. Walker).
We propose a deep (~1 Msec) exposure observation of the Sculptor dwarf spheroidal. The aim of the observations is to detect a narrow line, originating from a decay of dark matter (DM) particles in the DM halo of this dSph. Constraints from existing observations of dwarf and spiral galaxies, galaxy clusters with XMM, Chandra and Suzaku demonstrate that only such a dedicated deep exposure observation of DM-dominated objects can probe theoretically preferred range of DM parameters. Such an observation thus provides an unmatched capability to resolve fundamental problems of particle physics and cosmology. Additionally, this observation will allow to determine proper motion of dSph, study blue straggler stars and gas content.
2) Dark matter in very isolated galaxy pairs (O. Melnyk, A. Elyiv, J. Surdej).
We propose a total of 100 (2x50) ksec XMM observations of the two very isolated pairs of elliptical galaxies KPG276 and KPG387. These pairs do not show the presence of any significant neighbor within a distance of 1 Mpc. Since galaxy pairs constitute the general and most simple cases of galaxy groups, the main goal of our proposal is to detect some X-ray emission from the galaxy pairs and then to reconstruct in detail the corresponding dark matter distribution. Such observations will allow us to better understand the evolution and dark matter content at intermediate scales between individual galaxies and galaxy clusters.
3) X-ray Counterparts of Be Gamma-ray Binary Candidates (M. V. McSwain, M. Chernyakova, D. Malishev, M. De Becker, S. Williams and E.Coughlin).
The AGILE and Fermi missions have detected hundreds of unidentified GeV sources in the Galactic plane, but only a handful have been correlated with X-ray or optical counterparts. Several of these are high mass X-ray binaries that also exhibit MeV, GeV, and/or TeV emission, leading to a new class of "gamma-ray binaries". More than half of all HMXB contain Be stars, and likewise most of the known gamma-ray binaries are Be star systems. We have identified three new Be stars that may be associated with GeV point sources, and we propose XMM-Newton observations to measure the position, flux, and spectral properties of the X-ray counterparts. Our modest time request will help identify several unknown GeV point sources, potentially doubling the number of known Be/gamma-ray binaries.
4) Multiwavelength search of new gamma-ray loud binaries (A. Neronov, D. Malishev, M. Chernyakova).
This project is devoted to the study of gamma-ray-loud binary systems (GRLB). These systems form a new sub-class of X-ray binaries in which interaction of an outflow from a compact object (a neutrons star or a black hole) with the wind and radiation emitted by the massive companion star leads to the production of very-high energy (VHE) gamma-ray emission. Currently only 5 systems of this type are known. This proposal is aimed at the search of new representatives of this class of binary systems. Our goal is to understand general physical mechanisms responsible for the "gamma-ray loudness" of X-ray binaries. We have selected 5 GRLB candidate sources based on Fermi data (sources in the Galactic Plane visible above 100 GeV, with X-ray and/or radio counterpart). One of these systems, 1FGL J2107.5+5202c, was recently observed by Swift. For other sources no high-quality X-ray data are available. We propose to observe the four candidate GRLBs with XMM-Newton to identify the X-ray counterparts of the gamma-ray sources and measure their spectral and timing properties. Based on this information we will be able to confirm or reject the hypothesis that these gamma-ray sources are GRLBs. For the one GRLB candidate which was already observed by Swift, we propose to study the detailed spectral and timing characteristics, in particular, search for variability on the orbital time scale (2.35 days).
September 03, 2010 New VIRGO course for advanced students.

The site have been totally updated. Hope you like our new design.
July 12, 2010 New possibility of organizing video-seminars in BITP VIRGO class.
During the current course of intensive seminars devoted to Standard Model, the new possibility of video-seminars from r.347 (VIRGO-room) of Bogolyubov Institute for Theoretical Physics has been adapted. It is organized using the free EVO software. It is possible to record the video in EVO format and play it using the special EVO player.
The archived video records from the course (~400-500 Mbytes per day) are located here.
June 26, 2010 The start of the new course of intensive seminars devoted to Standard Model of elementary particles.
The new course of intensive seminars devoted to Standard Model of elementary particles will take place 5-16 July, 2010 in r.347 (VIRGO-room) of Bogolyubov Institute for Theoretical Physics. The main aim of the course is to provide an extended overview of the Standard Model processes showing the exceptional strengh of "tree unitarity" condition. In particular, we will show that by using the requirement of tree unitarity one can easily restore the structure of Standard Model in electroweak, gauge and Higgs sectors. An overview of stong interactions will also be presented. Finally, by considering 1-loop corrections to quantum electrodynamics, we will consider the basics renormalization theory and will show that the Standard Model is renormalizable.
This course is exceptionally recommended for senior students fluent with classical field theory, quantum mechanics and the basics of quantum field theory. In addition, several preliminary seminars (taking place during 29 June - 1 July, 2010) will take place to explain the basics of quantum field theory.
The schedule of the course is available here. To participate off-line on this course (excluding lecturers), one should contact Dmytro Iakubovskyi (firstname.lastname@example.org), this is necessary to provide the "passage permit" to Bogolyubov Institute.

April 08, 2010 Second on-line workshop dedicated to SCOPES cosmological project
On Wednesday, April 7, the second on-line workshop dedicated to SCOPES cosmological project was organized. The details of this workshop are available here.
February 09, 2010 Discussion of the Prof. Gia Dvali's lecture set "Beyond the Standard Model"
The lecture set "Beyond the Standard Model" contains 5 video lectures given by prof. Gia Dvali (one of the most renowned scientists in this field) at CERN Summer School (in English). This set of lectures is selected as an _up-to-date review_ of the physics beyond the Standard Model.
These lectures are available on-line using the following links:
(the duration of each lecture is about 75 minutes).
We are going to discuss the _content_ of this lecture set on Friday, February 12, at room 347 (VIRGO-class) of Bogolyubov Institute for Theoretical Physics. The discussion starts at 11:00 a.m. After each lecture, we will have a break, so the "maximum" goal is to discuss all 5 lectures in the set during Friday.
After this lecture set, we have a preliminary agreement with Prof. Dvali about his lecture (live video, using facilities of BITP video-conference class) concerning the "application of unitarity principle to black holes and creation of black holes in accelerators". The lecture set "Beyond the Standard Model" will thus serve as an _introduction_ to Prof. Dvali's lecture.

November 03, 2009 The KPI computing cluster now becomes available for running the VIRGO.UA software
During the last several months, the VIRGO.UA team - A.Boyarsky, O.Ruchayskiy, V.Slyusar and V.Kuznetsov - has successfully adapted the computational environment of the computing cluster of the Kiev Polytechnical Institute, one of the largest computing clusters in the Ukrainian Academic Grid, for GADGET-II, a commonly used cosmological simulation code.
GADGET-II is used in many leading simulations of cosmological structure formation, such as Aquarius project and Millenium simulation.
The VIRGO.UA team will run GADGET-II in KPI for important research in frames of a new SCOPES project funded by the Swiss National Science Foundation.
After this development, cosmological and astrophysical calculations at the KPI cluster become available via the GRID technologies, thus effectively enlarging the capability of the Ukrainian Academic Grid.
November 01, 2009 The SCOPES Joint Research project, lead by M.Shaposhnikov (EPFL) and A.Boyarsky, in collaboration with Ukrainian, Swiss, Russian and Georgian colleagues, has been selected by the Swiss National Science Foundation and will be financed beginning from December 1, 2009.
The SCOPES Joint Research project, lead by M.Shaposhnikov (EPFL) and A.Boyarsky, in collaboration with Ukrainian, Swiss, Russian and Georgian colleagues, has been selected by the Swiss National Science Foundation and will start from December 1, 2009. The budget of this project is 240.000 Swiss francs. The VIRGO.UA members (V.Zhdanov, Yu.Shtanov, G.Ivashchenko, D.Iakubovskyi, A.Ivashko and S.Vilchinsky) are largely participating in this project.
Our congratulations to the participants of this SCOPES Joint Research project!
The main goal of this project is to study the properties of dark matter and dark energy and to constrain (or differentiate between) particle-physics models in which these phenomena find their description. For this purpose, we are going to study the clustering of matter on relatively small spatial scales (< 1 Mpc) at early cosmological epochs (2 < z < 5) by using the available recent data on the Lyman-alpha forest in the spectra of quasars. The development of structure is known to be rather sensitive to the mass of particles constituting dark matter and their primordial velocity distribution and to the current value and possible evolution of the dark-energy density; this will hopefully enable us to fix these important values in a model-independent way. One of the particle species that definitely contribute to dark matter today are relic cosmological neutrinos. Combining the upper bounds on the mass of electron neutrino with the results of neutrino oscillations experiments, one can conclude that the heaviest neutrino mass lies in the range between 0.05 eV to about 2 eV. The method of Lyman-alpha forest, on the other hand, is expected to give tighter cosmological constraints on this parameter, which would be very important both for particle physics and for our understanding of cosmology.
The model-independent results obtained in this way are going to be quite important for various particlephysics candidates for dark matter and dark energy. One of the tasks of this project will consist in testing and putting constraints on the parameters of a specific extension of the Standard Model in which several problems of particle physics and cosmology (including the problem of dark matter and dark energy) find their natural and unified resolution.
October 27, 2009 Mykola Malygin successfully passed the BITP examination in theoretical minimum

October 10, 2009 A new large observation proposal for XMM-Newton has been submitted by A.Boyarsky, D.Iakubovskyi in collaboration with C.Frenk and R.Hickox (Durham University), J.-W. den Herder (SRON) and others.
Yesterday, 9th October, the XMM-Newton Ninth Announcement of Opportunity (AO-9) has been closed. Our members Alexey Boyarsky and Dmytro Iakubovskyi, together with a large group of European scientists, have submitted a large observing programme for XMM-Newton requesting for about one-tenth (!) of XMM-Newton observing time for 2010-2011 campaign in order to observe two faint Dark Matter-dominated objects - Draco and Sculptor dwarf spheroidal galaxies. Such large amounts of observing time are only available to the most important proposals leading to substantial improvement of our knowledge about the fundamental physics.
The title of the proposal: "The search for decaying dark matter particles with deep exposure observation of dwarf spheroidal galaxies"
Authors: A.Boyarsky (BITP, Kiev), C.Frenk (Durham Univ., Durham), J-W. den Herder (SRON, Utrecht), R.Hickox (Durham Univ., Durham), D.Iakubovskyi (BITP, Kiev), O.Ruchayskiy (EPFL, Lausanne), M.Walker (Ohio State Univ.)
Abstract. We propose deep (~1 Msec) exposure observations of the Sculptor and Draco dwarf spheroidal satellites (dSph) of the Milky way. The aim of the observations is to detect a narrow line, originating from a decay of dark matter (DM) particles in the DM halo of these dSphs. The deep exposure dedicated observations of dSphs with XMM-Newton provide an unmatched capability to resolve fundamental problems of particle physics and cosmology with X-ray observations.
October 08, 2009 A.Boyarsky's talk about ScienseWISE project
The ScienceWISE project, driven by Alexey Boyarsky with a group of Swiss scientists, aims to develop a scientist-generated on-line knowledge base fully integrated into the physics arXiv.

September 15, 2009 A new paper of A.Boyarsky, D.Iakubovskyi, D.Malyshev and co-authors has been submitted to Science.
A new paper "New evidence for dark matter" authored by Alexey Boyarsky (BITP, Kiev and ETHZ, Zurich), Oleg Ruchayskiy (EPFL, Lausanne), Dmytro Iakubovskyi (BITP, Kiev), Denis Malyshev (DIAS, Dublin) and Andrea Maccio (MPIA, Heidelberg) has been submitted to Science http://en.wikipedia.org/wiki/Science_(journal). Below is the abstract of this paper.
Abstract. According to our present understanding, all galaxies and galaxy clusters are
hosted by dark haloes. An important question is whether properties of these
dark haloes depend on local environment or whether they are universal. To
answer this question we collect a comprehensive observational sample of dark
matter-dominated objects and suggest a new characteristic of a halo – the dark
matter column density. This quantity shows a universal behaviour for all observed
objects over eight orders of magnitude in mass, from dwarf galaxies to
massive clusters. We show that this behaviour is in excellent agreement with
numerical and theoretical predictions from the current cosmological concordance
model. This universality provides a new evidence for the existence of
dark matter on an unprecedented large mass range.
