The early evolution of massive black holes
Marta Volonteri

TL;DR
This paper reviews the early formation and evolution of massive black holes, exploring seed formation processes in small proto-galaxies and their connection to galaxy evolution.
Contribution
It provides a synthesis of physical processes and observational tests related to the formation of massive black hole seeds in the early universe.
Findings
Black hole seeds likely form in early cosmic epochs
Formation efficiency varies with galaxy potential wells
Observational tests can distinguish formation scenarios
Abstract
Massive black holes are nowadays believed to reside in most local galaxies. Studies have also established a number of relations between the MBH mass and properties of the host galaxy such as bulge mass and velocity dispersion. These results suggest that central MBHs, while much less massive than the host (~0.1%), are linked to the evolution of galactic structure. When did it all start? In hierarchical cosmologies, a single big galaxy today can be traced back to the stage when it was split up in hundreds of smaller components. Did MBH seeds form with the same efficiency in small proto-galaxies, or did their formation had to await the buildup of substantial galaxies with deeper potential wells? I briefly review here some of the physical processes that are conducive to the evolution of the massive black hole population. I will discuss black hole formation processes for `seed' black holes…
