Black Hole Gf 2.70
Sagittarius A*, abbreviated as Sgr A* (/ ˈsædʒ ˈeɪ stɑːr / SADGE-AY-star[3]), is the supermassive black hole [4][5][6] at the Galactic Center of the Milky Way. Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii. Sagittarius A* is a bright ...
The density at the center of a black hole is infinite (it's a famous "singularity" [1], which leads to difficulties in modern cosmology). On Earth, densities range from 10 -4 g/cm 3 for light gases to 0.001 g/cm 3 for aerogels and up to the heaviest substance, osmium, with a density of 22.61 g/cm 3.
A black hole with a mass on the order of solar mass has a density of about 10¹⁹ kg/m³, exceeding the nuclear density of 2 × 10¹⁷ kg/m³. And a supermassive black hole with a mass of 10⁹ solar masses has an average density of about 20 kg/m³, much less than the density of water (1000 kg/m³).

We present an analysis of the fundamental plane of black hole accretion, an empirical correlation of the mass of a black hole (M), its 5 GHz radio continuum luminosity (νLν), and its 2-10 keV X-ray power-law continuum luminosity (LX). We compile a sample of black holes with primary, direct black hole-mass measurements that also have sensitive, high-spatial-resolution radio and X-ray data ...
In the local Universe, a majority of large black holes reside in elliptical or lenticular galaxies. Their black hole masses (M•) are estimated primarily through a correlation between their central stellar velocity dispersion, σ, and the mass of the SMBH [5- 8].
Stellar evolution theory predicts a "gap" in the black hole birth function caused by the pair instability. Many presupernova stars that have a core mass below some limiting value, Mlow, after all pulsational activity is finished, collapse to black holes, while more massive ones, up to some limiting value, Mhigh, explode, promptly and completely, as pair-instability supernovae. Previous ...

The largest star in the Cygnus OB3 association has a mass 40 times that of the Sun. As more massive stars evolve more rapidly, this implies that the progenitor star for Cygnus X-1 had more than 40 solar masses. Given the current estimated mass of the black hole, the progenitor star must have lost over 30 solar masses of material. Part of this mass may have been lost to HDE 226868, while the ...
Sagittarius A (Sgr A) is a complex radio source located at the centre of the Milky Way Galaxy. It contains Sagittarius A*, the supermassive black hole at the heart of our galaxy. The first image of the black hole was released in May 2022.
