" The role of galaxy interactions and mergers for igniting AGNs in COSMOS "

John Silverman

(IPMU, Univ of Tokyo)


I will present our latest results that address the question, whether interactions and subsequent mergers of galaxies are an efficient mechanism by which black holes grow? We specifically use the zCOSMOS spectroscopic redshift survey to generate a large sample of kinematic galaxy pairs up to z~1 and the Chandra X-ray observations of COSMOS to identify those that host AGNs including the obscured population. I will further discuss the importance of mergers relative to other processes capable of supplying gas to the nuclear region thus available for accretion onto a central supermassive black hole.


Seminars are also held at JAC, CFHT, and IfA.
