Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
A central massive object (CMO) is a high mass object or cluster of objects at the centre of a large star system, such as a galaxy or globular cluster. In the case of the former, the CMO may be a supermassive black hole , a nuclear star cluster , or even both together.
The redshift of J0529-4351 is 3.962. The object itself is classified as a radio-quiet quasar.Fitting accretion models to the spectra yields an accretion rate of matter onto the black hole of 280 to 490 solar masses per year for an accretion disk around the black hole observed at an angle of zero to 60 degrees, with accretion occurring near the Eddington limit.

The physics technical term massive particle refers to a massful particle which has real non-zero rest mass (such as baryonic matter), the counter-part to the term massless particle. According to special relativity , the velocity of a massive particle is always less than the speed of light . [ 1 ]
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars.
In theoretical physics, an anti-de Sitter (AdS) black hole is a black hole solution of general relativity or its extensions which represents an isolated massive object, but with a negative cosmological constant.
