“…Black holes, once just fascinating theoretical predictions of how gravity warps space-time according to Einstein's theory, are now generally accepted as astrophysical realities, formed by post-supernova collapse, or as supermassive black holes mysteriously found at the cores of most galaxies, powering active galactic nuclei, the most powerful objects in the universe. …”

“…DWs that annihilate at temperatures ∼ 20–50 MeV with tensions ∼ (40–100 TeV)$^{3}$ provide as good a fit to both datasets as the astrophysical background from supermassive black hole mergers. DWs may decay into the Standard Model (SM) or a dark sector. …”

“…The only known examples of very high rate galaxies at z>6 are, with only one exception[5], quasar host galaxies[6,7,8,9], i.e. galaxies that host an accreting supermassive (~10(9) M(sun)) black hole that likely affects the host properties. …”

“…It is hypothesized that the most massive galaxies in the universe- "elliptical galaxies"- grow simultaneously with the supermassive black holes at their centers, giving us much stronger evidence that black holes control galaxy formation. …”
