Nearby ravenous black hole mirrors early-universe feeding frenzy

Astronomers observe a supermassive black hole at the center of SDSS J110546.07+145202.4 (about 1.8 billion light-years away) in a rapid accretion phase, launching jets and causing a roughly 20-fold increase in radio brightness over about eight years. The behavior resembles the vigorous feeding seen in the early universe, providing a nearby laboratory to study extreme accretion physics and jet production. The finding, published in The Astrophysical Journal (May), suggests such rapidly changing radio galaxies could help fill gaps in our understanding of early galaxy growth, with future SKA surveys expected to identify more transients.
