The role of accretion in high-redshift submillimeter galaxies
D. M. Alexander (University of Cambridge)
Deep surveys have uncovered a large population of luminous submillimeter emitting galaxies (SMGs) at z>1. Although it is generally believed that these galaxies host intense star-formation activity, there is growing evidence that a substantial fraction also harbor an Active Galactic Nucleus [AGN; i.e., an accreting super-massive black hole (SMBH)]. Using X-ray, optical, and infrared observations I will explore the role of SMBH accretion in the SMG population, including placing constraints on the energetic contribution from AGN activity and the growth of SMBHs.
