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.
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 ...
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 ... its companion galaxy indicate a complex interaction and star ...
