Mapping monsters: Data release unveils all-sky views of supermassive black holes

Data released by the Sloan Digital Sky Survey (SDSS) marks a landmark expansion in the study of accreting supermassive black holes (SMBHs). As part of the fifth generation of the survey (SDSS-V), the Black Hole Mapper (BHM) program is providing unprecedented insights into the masses, growth and physics of quasars and active galactic nuclei (AGN) across cosmic time.
