Astronomers studying a 2023 tidal disruption event around the supermassive black hole Swift J1727.8-1613 found that a substantial fraction of the star’s material is expelled back into space after being drawn in, suggesting black holes can regurgitate matter and that the outflow could rival the amount swallowed, challenging the idea that these cosmic behemoths simply gobble everything.
Using the James Webb Space Telescope, astronomers have detected a massive and multiphase outflow of neutral and ionized gas in the galaxy COSMOS-11142. The outflow is larger than typical values measured in local star-forming galaxies and likely plays a key role in the rapid quenching of star formation in the galaxy. The researchers suggest that the outflow is driven by active galactic nucleus feedback and that heating of the halo gas by radio-mode AGN feedback is required to maintain the galaxy in a quiescent state.
