Title: A Transformative Multi-Object AGN Reverberation Mapping Campaign: Improving Spectrophotometry

Abstract: Accurately measured masses of supermassive black holes (BHs) are cornerstones for understanding the coevolution of active galactic nuclei (AGN) and massive galaxies. Mass estimates for distant BHs are tied to relationships derived from <50 AGN at z<0.3 with masses measured from reverberation mapping (RM). In RM, a virial mass is measured by properly combining an emission-line width with the distance of the line- emitting region from the BH, determined from the time lag between variations of an AGN's ultraviolet/optical continuum and variations of the emission line. Our pioneering multi-object AGN RM campaign (the singular opportunity this decade) on a uniform, magnitude-limited sample of 850 AGN will potentially revolutionize this field using 30 awarded epochs of SDSS-BOSS spectroscopy plus photometric monitoring data: it will yield \gtrsim 100 RM BH masses at z<3, more than measured in all previous RM campaigns, and enable an array of important AGN and non- AGN science. We here propose a total of 6 nights of KPNO-4m/MOSA multi- color imaging in 2014A of our RM field to accompany our main photometric component and to provide systematics control on spectrophotometry.
