Dynamics of Kicked and Accelerated Massive Black Holes in Galaxies
A study is made of the behavior of massive black holes in disk galaxies that have received an impulsive kick from a merger or a sustained acceleration from an asymmetric jet. The motion of the gas, stars, dark matter, and massive black hole are calculated using the GADGET-2 simulation code. The massive black hole escapes the galaxy for kick velocities above about 600 km s or accelerations above...
متن کاملGalaxies and Black Holes
The idea that supermassive black holes are generic components of galactic nuclei has come to be widely accepted, due largely to the secure detection of 10 6 − 10 9.5 M⊙ dark objects at the centers of about a dozen galaxies. 1 The mean mass of these objects – of order 10 −2.5 times the mass of their host galaxies – is consistent with the mass in black holes needed to produce the observed energy ...
متن کاملSatellite Accretion onto Massive Galaxies with Central Black Holes
Minor mergers of galaxies are expected to be common in a hierarchical cosmology such as ΛCDM. Though less disruptive than major mergers, minor mergers are more frequent and thus have the potential to affect galactic structure significantly. In this paper we dissect the case-by-case outcome from a set of numerical simulations of a single satellite elliptical galaxy accreting onto a massive ellip...
متن کاملWhy Massive Black Holes Are Small in Disk Galaxies ?
A potential mechanism is proposed to account for the fact that supermassive black holes (SMBHs) in disk galaxies appear to be smaller than those in elliptical galaxies in the same luminosity range. We consider the formation of SMBHs by radiation drag (Poynting-Robertson effect), which extracts angular momentum from interstellar matter and thereby drives the mass accretion onto a galactic center...
متن کاملBlack holes and massive remnants.
This paper revisits the conundrum faced when one attempts to understand the dynamics of black hole formation and evaporation without abandoning unitary evolution. Previous efforts to resolve this puzzle assume that information escapes in corrections to the Hawking process, that an arbitrarily large amount of information is transmitted by a planckian energy or contained in a Planck-sized remnant...
