Wissenschaftliches Kolloquium des IPP in Garching und Greifswald mit Videoübertragung
Over the last 50 years the existence of black holes has been established by different astrophysical means: the dynamics of stars and gas, emission from accretion disks surrounding them and gravitational waves. Black holes appear to exist over a vast range of masses, from a few times the mass of the Sun to a few billion Solar masses. But in many circumstances black holes have remained undetectable by current detection efforts, and we may just see the tip of the population iceberg. I’ll discuss some of the ongoing and upcoming efforts (including our own) to detect new parts of the black hole population. And I’ll sketch what this implies for their origin: When do massive stars leave black holes behind? Do all black holes in the Universe ultimately trace back to stellar remnants?
