New research shows weak black hole activity in red geyser galaxies prevents star formation despite ample gas, using observations of inflows, outflows, and galaxy interactions.
Astronomers using W.M. Keck Observatory on Mauna Kea have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence ...
New JWST observations show that supermassive black holes formed rapidly from direct gas collapse, creating massive “seeds” that explain how billion-solar-mass giants emerged just a few hundred million ...
