JWST Black Hole Discoveries

Multiple breakthroughs: overmassive early black holes, Virgil LRD, Hatchling quasar, ancient quasars, merging black holes at high redshift. New insight: Saguaro galaxy (z=2) as lower-redshift analog for little red dots, suggesting they are a phase of ordinary galaxies. Competing models for little red dots. XRISM reveals powerful quasar winds.
