SUMMARY:Reverberation mapping the inner environments of AGN\, Astronom
 y Colloquium\, Yasaman Homayouni\, Penn State University
DESCRIPTION:Reliable measurements of black hole mass and accretion-dis
 k structure are critical to understanding the growth history of black 
 holes and galaxy evolution over cosmic time. Beyond the local Universe
 \, the gold standard for black hole mass and accretion-disk structure 
 is reverberation mapping. I will present the latest results from the S
 loan Digital Sky Survey Reverberation Mapping (SDSS-RM) project and sh
 ow how it has transformed our understanding of supermassive black hole
 s by dramatically expanding the number of quasars with reliable mass a
 nd accretion structure at z > 0.3. I will also present a promising new
  method for reliably measuring mass and accretion structure of early b
 lack holes using direct accretion-disk structure measurement from futu
 re massive time-domain quasar studies with SDSS-V and LSST.
