XRISM captures a monster black hole’s awakening blasting a starburst galaxy with fast winds
XRISM observed the waking of the supermassive black hole IRAS 05189-2524 in a merging, star-forming galaxy, detecting high-velocity, bullet-like outflows up to about 0.14c that carry far more energy than slower winds. The finding shows how black-hole winds can shape the host galaxy and regulate star formation, shedding light on the co-evolution of galaxies and their central engines.
