They found a type of ultra-powerful galaxy that gobbles up everything around it. Its energy is so intense that, if it were ...

By revealing a massive radio jet in the early universe, J1601+3102 offers a rare snapshot of early quasar activity.

is considered to be smaller than typical quasars, which can reach masses that are billions of times heavier than our star. “This seems to indicate that you don’t necessarily need an ...

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 ...

ABSTRACT We present new Hubble Space Telescope (HST) Wide Field Planetary Camera images of the poststarburst quasar UN J1025−0040, which contains both an active galactic ... in UN J1025−0040 and its ...

(M. Garlick/NOIRLab/NSF/AURA via AP) CAPE CANAVERAL, Fla. (AP) — Telescopes around the world have spotted a monster radio jet streaming from a quasar dating back to the first 1 billion years of the ...

Astronomers have identified the brightest object ever observed in the universe, a quasar named J0529-4351. This quasar is 500 trillion times brighter than the Sun, setting a new record for ...

Chinese astronomers have investigated quasar candidates from the DESI Legacy Surveys (DESI-LS) photometry catalog. As a result, they detected 19 strongly-lensed, dual and projected quasars.

Surprisingly, the black hole driving this colossal jet is modest by quasar standards, weighing 450 million times the mass of ...
