The most distant radio-loud quasar discovered

In a recent study, an international team of astronomers presents the discovery of PSO J172.3556+18.7734—a highly accreting radio-loud quasar at a redshift of approximately 6.82. This is the most distant radio-loud quasar ...

Study investigates emission from a distant red quasar

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, an international team of astronomers has performed observations of HSC J120505.09−000027.9—the most distant red quasar so far detected and found ...

Three high-redshift quasars detected by Chandra

Using NASA's Chandra spacecraft, astronomers have discovered three new ultraviolet-bright radio-quiet quasars at high redshift and measured their basic X-ray properties. The newly found quasi-stellar object turns out to be ...

Five new giant radio galaxies discovered

With the help of citizen scientists, astronomers have detected five new giant radio galaxies (GRGs). The new GRGs have sizes ranging from 2.3 to 2.6 million light years, and have been identified at redshift between 0.28 and ...

Two new high-redshift red quasars discovered

Using the Subaru Telescope, astronomers have identified two new dust-reddened (red) quasars at high redshifts. The finding, detailed in a paper published July 16 on the arXiv pre-print server, could improve the understanding ...
