European astronomers report the detection of a new powerful radio-loud quasar at a redshift of about 5.32. The newfound object, designated PSO J191.05696+86.43172, turns out to be one of the brightest radio quasars identified ...
Astronomers from the Steward Observatory in Tucson, Arizona and elsewhere report the detection of a new massive protocluster. The structure was found around a luminous quasar known as J0910–0414. The discovery was detailed ...
A new study published in Physical Review Letters outlines how scientists could use gravitational wave experiments to test the existence of primordial black holes, gravity wells formed just moments after the Big Bang that ...
