A Wobbling Black Hole Jet Could Starve Its Galaxy of New Stars
Astronomers have observed a precessing, high-velocity jet from a supermassive black hole in VV 340a heating and ejecting gas across the galaxy, potentially quenching star formation; the outflow rate is about 19 solar masses per year, and multiwavelength data from JWST, Keck, VLA, and ALMA reveal how such black-hole activity can reshape galactic evolution.
