The Sloan Digital Sky Survey has released new data from its Black Hole Mapper program, part of the SDSS-V generation, providing comprehensive all-sky observations of supermassive black holes. The program focuses on studying accreting supermassive black holes through observations of quasars and active galactic nuclei, offering detailed measurements of their masses, growth rates, and physical properties across different epochs of cosmic history. This represents a significant expansion in the scale and scope of supermassive black hole research.


This data release enables astronomers to better understand how supermassive black holes evolve and influence galaxy formation throughout the universe's history. The comprehensive mapping approach will help researchers identify patterns in black hole growth and activity that were previously difficult to detect with smaller, more limited surveys.


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.
