However, as these quasars and their host galaxies continue to merge, they are expected to combine their resources—stars, gas, and black holes—into a single, extraordinarily massive galaxy.

Abstract: Quasars in the Age of Time-Domain Astronomy: Black hole feeding, visible as quasars, is a critical ingredient in many fields from galaxy evolution to multi-messenger gravitational wave ...

The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining their data with other experiments shows signs that the ...
