Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active ...

Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an active black hole, more ...

The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass was ...

A colossal census of the cosmos has more than tripled the number of active black holes known to reside in miniature galaxies and found the biggest haul of middleweight black holes to date. That’s ...

In 2008, Marta Volonteri helped develop a radical proposal: Astronomers should search the smallest of galaxies for colossal black holes—hulking behemoths weighing many thousands of solar masses. If ...

The Dark Energy Spectroscopic Instrument discovers a treasure trove of active black holes in dwarf galaxies and reveals that surprisingly few are of intermediate mass DESI is a state-of-the-art ...
