Formation of Supermassive Black Holes by Direct Collapse in Pregalactic Halos
We describe a mechanism by which supermassive black holes can form directly in the nuclei of protogalaxies, without the need for “seed” black holes left over from early star formation. Self-gravitating gas in dark matter halos can lose angular momentum rapidly via runaway, global dynamical instabilities, the so-called “bars within bars” mechanism. This leads to the rapid buildup of a dense, sel...
متن کاملObservational Evidence for Black Holes
Astronomers have discovered two populations of black holes: (i) stellar-mass black holes with masses in the range 5 to 30 solar masses, millions of which are present in each galaxy in the universe, and (ii) supermassive black holes with masses in the range 106 to 1010 solar masses, one each in the nucleus of every galaxy. There is strong circumstantial evidence that all these objects are true b...
متن کاملObservational Features of Black Holes
Recently Holz & Wheeler [59] considered a very attracting possibility to detect retro-MACHOs, i.e. retroimages of the Sun by a Schwarzschild black hole. In this paper we discuss glories (mirages) formed near rapidly rotating Kerr black hole horizons and propose a procedure to measure masses and rotation parameters analyzing these forms of mirages. In some sense that is a manifestation of gravit...
متن کاملBlack Holes, Wormholes, and Gravitational Collapse
We study a possibility of the dynamical formation of traversable wormholes from gravitationally collapsing exotic matter clouds. For generic metric ansatz of exterior spacetimes, a crucial constraint that black holes and wormholes should satisfy is obtained through the junction conditions on the edge. As a result, it is shown that the wormhole geometry cannot be formed by following the usual Op...
متن کاملGravitational Collapse, Black Holes and Naked Singularities
This article gives an elementary review of gravitational collapse and the cosmic censorship hypothesis. Known models of collapse resulting in the formation of black holes and naked singularities are summarized. These models, when taken together, suggest that the censorship hypothesis may not hold in classical general relativity. The nature of the quantum processes that take place near a naked s...
