Quasar
5 reportsScientific coverage devoted to Quasar addresses environmental interactions, while also considering population context and mass estimate. One line of support comes from distance or orbit estimates, and a separate test comes from model comparison; together they clarify population context, but the result is bounded by the possibility that limited viewing geometry and indirect measurements can leave competing explanations.
AI reconstructs black hole jet motion from decades of radio data
A new AI-driven analysis of 27 years of radio telescope data has produced the sharpest reconstruction yet of a black hole jet, revealing unexpected details about plasma motion in the blazar 3C 345
Fading Radio Galaxies Reveal What Happens When Black Holes Go Quiet
A new study using MeerKAT, LOFAR, and the Jansky Very Large Array has identified a population of galaxies with fading radio lobes, offering insight into the late stages of supermassive black hole activity
Webb Telescope Spots Candidate Black Hole Star in Early Universe
Astronomers using the James Webb Space Telescope have identified a luminous, solar-system-sized object from 660 million years after the Big Bang, offering the strongest evidence yet for a hypothesized 'black hole star' class.
Black Hole Winds Drive Turbulence Far Beyond Host Galaxy
Observations with Japan's XRISM X-ray satellite reveal that outflows from a supermassive black hole in a distant quasar are far more powerful than previously estimated, stirring hot gas across intergalactic space
Chandra X-ray Observatory reveals hot gas from early quasar
NASA's Chandra X-ray Observatory has detected extremely hot gas surrounding a distant, radio-quiet quasar, offering new insight into the formation of galactic cluster atmospheres in the early universe
