Abstract

Measuring the mass of the supermassive black holes (SMBHs) found at the center of nearly every massive galaxy is essential to our understanding of the cosmic evolution of these exotic objects in the Universe. However, at great cosmological distances, it is extremely challenging to measure SMBH masses. A primary technique, called "reverberation mapping" (or echo mapping), is to measure the light echo from the…
