Research Interests

Dr. Bugaev works in the field of High Energy Astrophysics. Dr. Bugaev uses gamma-ray observations to study the astrophysics of supernova rem- nants (SNR). Gamma-rays created in Cosmic Ray (CR) interactions with interstellar medium are not deviated by magnetic fields and hence help to locate the origin of accelerated particles. SNRs are believed to be the likely acceleration sites in the Galaxy for CR. The detection of gamma-rays from SNRs can be used to determine which types of SNR and which astrophysical conditions lead to efficient particle acceleration of the hadronic component of CR.

The primary goals of studying SNRs are to get insights on their magnetic fields (strength and geometry), diffusion coefficients, and other parameters governing the acceleration process, as well as to study the properties of the interstellar medium surrounding SNRs. Dr. Bugaev’s research uses the data from the satellite borne gamma-ray telescope Fermi, and the ground based TeV gamma-ray telescope VERITAS.

Dr. Bugaev works on several future gamma-ray and neutrino experiments. He participates in the R&D for the next-generation ground based Cherenkov Telescope Array (CTA) experiment. The main objectives of CTA will include observing the decay of dark matter particles at the center of our Milky Way Galaxy and in the centers of nearby dwarf galaxies and tests of Lorentz Invariance. Dr. Bugaev is a co-chair of a simulation working group of US affiliated institutions-members of CTA (CTA-US). He is working on the optimization of the design configuration for CTA.

Another research focus in the frame of CTA concerns the designs of the mechanical and optical systems of the telescopes to be contributed by CTA- US to the CTA Consortium.

Dr. Bugaev participates in the simulations for the next-generation Ultra High Energy Neutrino Detector ARIANNA to maximize the sensitivity of the instrument and makes atmospheric modeling to optimize the design of wind turbines providing power to the experiment.
