Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Michael McDonald, Brian R. McNamara, Michael S. Calzadilla, Chien-Ting Chen, Massimo Gaspari | Summary: We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live at the centers of […]
