Драге колеге,

У петак 6. марта, у 11 сати, у сали 360 Института за физику, одржаће се 
семинар наше групе.

Колега Андреј Јегоров (Институт за физику у Београду) причаће нам о теми 
"Black holes: implications for dark matter searches and theories of 
gravity".

Aпстракт предавања на енглеском: My talk will contain two major parts. 
The first part will be dedicated to my new work about detection 
prospects for heavy DM particles (WIMPs) near supermassive black holes 
(SMBHs). SMBHs are expected to form density spikes of annihilating DM. 
Such spikes may be detectable in the gamma-ray band even in the case of 
the heaviest WIMPs, which are not observable otherwise. Only two closest 
SMBHs are shown to be relevant for WIMP searches: MW* and M31*. I 
estimated the sensitivity of upcoming Cherenkov Telescope Array to the 
potential WIMP signal from those targets. The second part of my talk 
will review semi-qualitatively the implications and possibilities of BH 
observations for testing theories of gravity (including quantum ones). 
Thus, I cover current and future observations of gravitational waves, 
SMBH shadows, isolated stellar BHs, MW nuclear star cluster and others. 
Finally, a summary of the current synergy between theory and 
observations will be given.

Семинар ће бити одржан на Енглеском језику.

Све најбоље,

Игор Прлина
