11. listopadu 2013: With Dr Nadine Neumayer, ESO Exactly 50 years ago, the discovery of quasars revolutionised astronomy. Black holes turned from a theoretical idea into reality. Today, black holes seem to be ubiquitous at the centres of massive galaxies. They can remain dormant, as in our galaxy, the Milky Way, or they can be actively accreting and “swallowing” the matter, gas and stars, surrounding them and in the process becoming bright, active galactic nuclei, of which quasars are the most extreme example. Surprisingly, astronomers have found a very tight relationship between the mass of the central black hole, and the mass of its host galaxy. They believe that the reason for this tight relationship is the common origin and evolution of these two objects. Dr Nadine Neumayer, from ESO, will discuss with the guests of Café & Kosmos when and how black holes get to the centre of galaxies in the first ...
