Ny analyse fører til fundamentalt anderledes syn på supertunge sorte huller
I midten af næsten alle galakser ligger et supertungt sort hul. Nogle af disse sluger gas og støv omkring dem og udstøder den overskydende energi som kraftige jets, der ses som kvasarer på tværs af det observerbare Univers. En ny undersøgelse ledet af astronomer ved Cosmic Dawn Center har re-analyseret denne proces hjælp af nye teknikker — og resultaterne kan ændre vores opfattelse af disse kosmiske monstres kostvaner.

New analysis leads to a fundamentally different view of supermassive black holes
In the center of most galaxies lies a supermassive black hole. Some of these are actively feeding on the gas and dust around them, expelling excess energy as powerful jets that are seen as quasars across the entire observable Universe. A new study led by astronomers at the Cosmic Dawn Center reviewed this process using new techniques — and the results may change how we think about the diets of these cosmic behemoths.
