Supermassive black holes
1 OF ALL the legacies of Einstein’s general theory of relativity, none is more fascinating than black holes. While we now almost take their existence for granted, for much of the 20th century black holes were viewed as mathematical curiosities with no counterparts in nature. Einstein himself never believed in black holes and wrote two papers in which he argued against their existence. Einstein’...

متن کاملThe Self–regulated Growth of Supermassive Black Holes
We present a series of simulations of the self–regulated growth of supermassive black holes (SMBHs) in galaxies via three different fueling mechanisms: major mergers, minor mergers, and disk instabilities. The SMBHs in all three scenarios follow the same black hole fundamental plane (BHFP) and correlation with bulge binding energy seen in simulations of major mergers, and observed locally. Furt...
متن کاملThe Growth of Supermassive Black Holes and QSO Formation
A novel mechanism to build up a supermassive black hole (SMBH) is proposed. Here, relativistic radiation-hydrodynamic processes are considered from a galactic scale to a horizon scale. In the present scenario, the mass of a SMBH is predicted to be in proportion to the bulge mass, and it turns out that the SMBH-to-bulge mass ratio is basically determined by the nuclear energy conversion efficien...
متن کاملSpin, Accretion and the Cosmological Growth of Supermassive Black Holes
If supermassive black holes (SMBHs) are the energy sources that power quasars and active galactic nuclei, then QSO SDSS 1148+5251, the quasar with the highest redshift (zQSO = 6.43), hosts a supermassive black hole formed within ∼ 0.9 Gyr after the Big Bang. This requirement places constraints on the cosmological formation of SMBHs, believed to grow from smaller initial seeds by a combination o...
