So far, the research has assumed that supermassive black holes primarily grow through violent galaxy crashes. New observation data now draw a much calmer picture and tilt this old principle of astrophysics. read more on t3n.de

No violent collision necessary? An analysis of 2,435 disk galaxies shows that central black holes, even in galaxies with no visible starwurst, follow the same relationship to the entire mass of stars as in systems with bulge. This suggests that slow processes in the galaxy can drive a significant part of the growth of supermassive black holes. Oxford (England). In the center of many [...] The post Black holes can grow even without large fusions …

Astronomers analyzed 2,435 galaxies hosting black holes that actively feed on data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 galaxies "without swelling", i.e. systems with little or no central stellar bulge. Their article, published in Monthly Notices of the Royal [...]
