Accretion onto Supermassive Black Holes: Fuel for Quasars

, 2011
Quasars are the most luminous objects in the Universe. Strict size and mass constraints for the central emitting region in these objects present astronomers with the problem of identifying their source of energy.

Supermassive black holes as sources for LISA

, 2007
. I briefly discuss some issues relevant for the formation of supermassive black holes and give estimates of the event rates for the emission of gravitational waves by coalescing supermassive black hole binaries.

Learning about gravity from imaging supermassive black holes

I will discuss how the first images of the supermassive black holes M87* and Sgr A* were obtained by the EHT collaboration. In particular, I will describe the theoretical aspects that have allowed us to model the dynamics of the plasma accreting onto the

Dynamics around supermassive black holes

, 2007
The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand.
