Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and
ColorBlackHoleBlack holes are seen as the engines of active galaxies. They suck in gas and stars from their surroundings and collect the material initially in the accretion disk, where most of the radiation produced by the galaxy comes from. Up to now, the proof that these disks exist has ...
Gravastars, hypothetic astrophysical objects, consisting of a dark energy condensate surrounded by a strongly correlated thin shell of anisotropic matter, have been proposed as an alternative to the standard black hole picture of general relativity. Observationally distinguishing between astrophysical black...

[21]were found to rely on an overly optimistic model for the black hole accretion rate[22]and continue to be updated as our understanding of accretion improves[23]. Similarly, uncertainty in the modeling of the PBH merger rate has led to several revisions of the bounds from gravitational ...
“We were the first to image this elusive disk and study its rotation,” said Elena Murchikova, a member in astrophysics at the Institute for Advanced Study in Princeton, New Jersey,in a statement. “We are also probing accretion onto the black hole. This is important because this is our...
We selected a sample of 28 Type 1 active galactic nuclei for which a black hole mass has been inferred using the reverberation mapping technique and single epoch scaling relations. All 28 sources show clear evidence of the “Big Blue Bump” in the optica

the central engines of the stellar mass accreting X-ray binary systems are thought to be primarily and generally from accretion disks (and coronae) and collimated jets, respectively, which provide an observational avenue to investigate the disk and jet correlation with the black hole mass [39]....
In this case, no stable circular motion is possible for 𝑟<𝑟𝑚𝑠r<rms, and we assume here that the inner radius of the accretion disk could at least be placed by 𝑟𝑚𝑠rms in Equation (4). Note that now, 𝑟𝑖𝑛rin is a function of the black hole spin a (see Se...
