HSE Physics Students to Help Create Map of Universe
The Higher School of Economics is welcoming its first class of students to the Faculty of Physics. The new faculty is unique in that it fosters a close relationship between education and science. At the Space Research Institute, for instance, future master’s students will create devices to study space plasma, analyse data from satellites, and learn to determine space weather.
The HSE Faculty of Physics has six joint departments, including the Department of Space Physics, which was created in partnership with the Space Research Institute of the Russian Academy of Sciences. This is the main academic institute for the study and use of outer space.
The Space Research Institute was founded in 1965 and currently conducts experimental and theoretical scientific work in fields such as astrophysics, the physics of planets and small bodies in the solar system, solar physics and the physics of solar-terrestrial connections, cosmic plasma, and nonlinear geophysics. The institute also develops programmes for scientific space research and develops and tests different apparatuses for research projects approved by the Russian Academy of Sciences and the Federal Space Agency.
With the Space Research Institute, the Higher School of Economics is planning to train specialists in two key areas: high-energy astrophysics and space plasma physics. This includes solar physics.
What the Universe Is Made of
Space plasma physics is a key area in the institute’s theoretical and experimental research. Space plasma appeared during the first moments of the birth of the universe after the Big Bang and is one of the most widespread states of matter in nature. Nearly 99% of matter in the universe is in a plasma state (not counting dark matter and dark energy, the nature of which is still unclear). That includes all stars, including the Sun, as well as the interstellar and interplanetary medium and even the upper layers of planet atmospheres. It is plasma processes in particular that control solar activity and its consequences – geomagnetic activity on Earth, also known as space weather. Research can be conducted on these processes with the help of long-distance spectral methods, optic telescopes, radio telescopes, outer-atmospheric X-rays, and gamma-observatories on space vehicles.
Staff from the space plasma division of the Space Research Institute have participated in work on practically all Soviet and Russian plasma- and planet-related projects. This includes Intercosmos; Cosmos; Prognoz; the automatic interplanetary stations Luna, Venera, Mars, and Fobos; and the space stations Salyut, Mir, the ISP, and others.
In their solar physics research, scientists from the Space Research Institute along with British colleagues from the University of Warwick won a grant from the British Council to study the seismology of the solar corona’s active regions. The researchers are planning to step closer towards a key objective in solar physics – assessing free magnetic energy in flare regions. This knowledge is necessary to evaluate the energy given off by flares, as well as their impact on the Earth and on space infrastructure. HSE students who choose to conduct research in this field will be able to participate in partner research projects and gain experience through international internships.
How Galaxies Evolve
The next field that will be developed at HSE thanks to the partnership with the Space Research Institute is high-energy astrophysics. Research in this area began at the institute in the early 1980s under the leadership of Yakov Zeldovich, one of the creators of relativistic astrophysics. This is a new area of science in which the theory of general relativity is applied to astrophysical objects.
Since the division first started within the Space Research Institute, the Russian Academy of Sciences, along with Russian and international partners, have carried out a number of astrophysics-centred projects to study the universe. This includes the Roentgen Orbital Observatory on MIR, the Granat Observatory, and the Integral Observatory. The Integral still operates and currently conducts hyperfine gamma spectroscopy on cosmic radiation and constructs images of the sky in an energy range between 15 keV and 10 MeV.
Other projects include the RTT150 Russian-Turkish 1.5-m Telescope, which is used to provide on-the-ground support to space projects in the field of high-energy astrophysics (INTEGRAL and in the future SPEKTR-RG). The objective is to build a map of the universe where all large galaxy cluster can be indicated, thus helping answer the question of how galaxies evolve.

Plans for the Future
‘There is one more prospective field that we are planning to develop – space navigation and ballistics,’ adds Lev Zelenyi, who is the Director of the Space Research Institute of the Russian Academy of Sciences and the Head of the Joint Department of Space Physics. ‘What is necessary in this field is an excellent knowledge of mathematics, which the Higher School of Economics is famous for, as it now has one of the best mathematics faculties in the country. And we want to achieve the same results in physics.’
With the discovery of gravitational waves, scientists have gotten another channel with which to learn more about the universe. It is in this field in particular, as well as in cosmology (a science that studies the formation of the solar system), where interesting discoveries will be made in the years ahead, Professor Zelenyi says.
A Special Environment
‘One can do nothing but envy the students who will come study this since the amount of research is clearly growing in the field of astronomy, astrophysics, and planetary physics. Because of this, HSE is certainly making the right decision in opening a physics faculty right now, and I think that with time it will become one of the institute’s adornments,’ Mr Zelenyi notes.
‘The master’s students who are joining us this year are headed for specific instructors, as they already know what they want to do,’ adds Maksim Dolgonosov, Deputy Head of the Joint Department of Space Physics and Senior Researcher with the Space Research Institute. ‘We are happy with the way our relationship is unfolding with HSE. For us this represents an opportunity to supply our organisations with more young and qualified staff. After all, you need a special environment in order to produce a researcher who has the skills to conduct his or her own future work independently and one with a well developed scientific view of the world. This environment has to be flexible, responsive, and capable of sensitively reacting to changes. It also has to factor in the interests of both students and scientific organisations. This is precisely the atmosphere we are going to create with HSE. We already have examples of our close partnership with the school. We won a grant to invite a foreign researcher to the school thanks to the HSE Teaching Excellence Initiative, and we organised a lecture series by University of Warwick Professor Valery Nakariakov. He lectured on solar physics, and we invited future HSE master’s students to attend.’
According to one of the applicants to the faculty’s master’s programme, Evgeny Belezyorov, he became familiarised with HSE during one of the university’s summer school in physics for those applying to the master’s programme. It was during this time that Evgeny met the faculty’s Deputy Dean Alexander Kostinskiy.
‘I was interested in solar physics, which is why I chose the space physics department and met with Maksim Dolgonosov, who is responsible for the Space Research Institute’s work with students. He showed me the laboratories and introduced me to some researchers with the institute. Before that I had visited other universities, but no one really struck up a conversation with me there, while I got a different impression here. Today I stopped by the department to talk with Ivan Zimovets, who I hope will one day be my academic supervisor.’
On Cosmonautics Day, the HSE News Service spoke with the participants of the CubSX-HSE project, which recently launched a satellite into Earth orbit. Students and staff from the HSE Moscow Institute of Electronics and Mathematics (MIEM) spoke about their project and impressions of their trip to Baikonur.
LHCb (Large Hadron Collider beauty) collaboration, one of the LHC (Large Hadron Collider) experiments, reported that their detector has identified particles that have not previously been detected in physics experimentally – excited omega baryons (Ω-b). Just several years ago, detecting such particles in LHC was believed to be next to impossible. Among proton particles, the excited ‘charmed omegas’ were preselected by an algorithm created by staff from the HSE Laboratory of Methods for Big Data Analysis and Yandex LLC. IQ.HSE talked to Denis Derkach and Fedor Ratnikov about their collaboration’s ‘fresh catch’ and about the point of ‘fishing’ on LHCb in general.
Alexey Starobinsky, a professor of physics at HSE University and a fellow at the Landau Institute for Theoretical Physics at the Russian Academy of Science, has been awarded the Dirac Medal of the ICTP, a prestigious prize awarded annually by the Abdus Salam International Center for Theoretical Physics. HSE News Service spoke with the laureate about his path to international recognition, his students, and the award.
Students in the Faculty of Physics, one of the newest departments at HSE, will find a homey atmosphere, understanding teachers, and the opportunity to engage in science from the first year of studies. Physics students Arslan Galiullin (2nd year) and Sofia Lopatina (1st year) will be our guides for this instalment of the Open House project.
During the ‘Big Challenges’ session at the Sirius Educational Centre, five high school students, under the supervision of mentors from MIEM HSE, assembled a small artificial earth satellite. The participants of the research session were young finalists of a nationwide competition held by the educational centre. All five of the students are Olympiad champions and team members of large-scale projects.
The HSE University competition committee has announced the winners of an international competition for new physics laboratory proposals. Two proposed projects were selected: the Laboratory of van der Waals Heterostructures, headed by Davit Ghazaryan, and the Laboratory of Nanophotonics and Functional Materials, headed by Andrey Krasavin.
A team of researchers from Germany and Russia have demonstrated that long contraction of muscles in one hand increases involuntary reaction of the other one. Meanwhile, the time between muscle contractions in both hands decreases. The results of the study have been published in the paper ‘Inverse relationshipbetween amplitude and latency of physiological mirror activity during repetitive isometric contractions’ in Neuroscience.
The results of recent study conducted by the NASA Lunar Reconnaissance Orbiter, the agency’s automatic interplanetary station, show the existence of a ‘permafrost’ near the poles of the Moon with a relatively high content of water ice (up to 5% by weight). It is believed that water ice could supply a life support system for the future Russian Lunar Station and that it could also produce hydrogen-oxygen fuel for flights into deep space.
At the general meeting of the Russian Academy of Sciences (RAS), held on April 23, research by Alexander Kostinskiy, Vladimir Rakov and Mikhail Andreev conducted in collaboration with their colleagues from academic institutes on the modeling and development of lightning was acknowledged as one of the most significant Russian scientific achievement in 2018.
Researchers from HSE University and Yandex, as part of the LHCb collaboration at CERN, have been the first to discover CP violation in charm meson decays.
