Wykłady odbywają się w okresie od października do czerwca, raz w miesącu, w poniedziałki o godzinie 18:00.
Black holes are among the most enigmatic objects in the Universe, and their mergers are some of the most energetic events ever observed. With the advent of gravitational wave astronomy, we now have a new window into these cosmic collisions. This talk explores how star clusters—dense environments where stars are born and interact—serve as natural factories for producing merging black holes. We begin with an introduction to black holes, gravitational waves, and the groundbreaking discoveries made by the LIGO-Virgo-KAGRA collaboration through ground-based gravitational wave detectors. Then, we delve into the physics of star clusters, discussing how dynamical interactions in these dense and crowded environments lead to black hole binaries that eventually merge due to gravitational wave emission. Through computer simulations, we explore how these binaries form and evolve, shedding light on the origin of some of the black hole mergers detected by gravitational wave observatories.By understanding the role of star clusters, we can better interpret current observations and prepare for future discoveries with planned space-based gravitational wave detectors like LISA.

I will discuss how astronomers have studied the supermassive black hole that resides in the center of our Milky Way Galaxy, 25000 light-years from Earth. I will review the multi-band observations that have uncovered the black hole and also allowed us to study the stars and gas in its vicinity. I will also review black hole "feeding" --- both in the present and in the distant past, when the center of our Galaxy may have been much more active and bright.

Jakich metod używamy przy badaniu pobliskich planet? W jaki sposób możemy zbadać skład chemiczny i warunki fizyczne panujące w atmosferze gwiazdy? Czy możliwe jest zbadanie składu chemicznego odległych galaktyk? O tym wszystkim opowiem w swoim wykładzie.
