Distant quasar blasts ultraviolet winds at 0.3c, setting cosmic wind records
Astronomers report a distant quasar named J2318 powered by a 1.7-billion-solar-mass black hole emitting radiation-driven winds in ultraviolet light at speeds up to 0.3 times the speed of light—the fastest ultraviolet outflow observed. These extreme winds carry so much energy that they could push away gas and dust from the host galaxy, potentially quenching star formation and influencing galaxy evolution. The findings, derived from SDSS observations, were published in The Astrophysical Journal.
