The next Colloquium of the Astronomical Observatory will be held on Wednesday, December 24, at 1 PM in the Library.
Speakers: Dr Andrei Egorov, Senior research associate of the Institute of Physics in Zemun
Topic: Dark matter phenomenon: general review and indirect searches
Resume: I will review the discovery history of dark matter (DM), its role in early and present Universe with implications for DM models. Then I will talk about all main contemporary DM candidates: weakly interacting massive particles (WIMPs), axions, sterile neutrinos, primordial black holes and others. WIMP paradigm will be discussed in more details. In the second part I will tell about my work on indirect WIMP searches and constraints. This comprises the search near the Galactic center in microwave band, constraints from radio observations of Andromeda galaxy (M31). Another direction employs gamma-ray band: observations of M31 too and nearby supermassive black holes. The latter renders high relevance for heavy TeV-scale WIMPs. Finally I will summarize the global status of WIMP indirect searches and future possibilities for DM discovery.
