"The Joint Formation of
Bulges and Black Holes" |
|
The last 15 years or so have brought mounting evidence that bulges in disc galaxies are not just miniature elliptical galaxies surrounded by stellar and gaseous discs, as previous galaxy formation scenarios expected. Furthermore, different formation processes are found to lead to fundamentally different classes of bulges, namely classical and pseudo-bulges. Concurrently, we now know that the formation of a central supermassive black hole is intimately connected to the formation of its stellar host. In this talk, I will show new results based on a thorough analysis of nearly 1000 galaxies from the Sloan Digital Sky Survey. Our results indicate how different the formation processes of elliptical galaxies, classical and pseudo-bulges are, and how this have affected the growth of their central black holes. In addition, we provide observational constraints that have to be fulfilled by successful galaxy formation models. |
