A #UniversityofKansas #survey of a swath of the #cosmos using the #JamesWebbSpaceTelescope has revealed #activegalacticnuclei (#AGN)—#supermassiveblackholes that are rapidly increasing in size—are rarer than many #astronomers had assumed previously.

After almost seventy years of study, #astronomers are still fascinated by #activegalacticnuclei (AGN), otherwise known as quasi-#stellar objects (or “quasars.”) These are the result of supermassive #blackholes (SMBHs) at the center of massive #galaxies, which cause gas and dust to fall in around them and form accretion disks.
