The mass function of high redshift seed black holes
In this paper we derive the mass function of seed black holes that result from the central mass concentrated via disc accretion in collapsed haloes at redshift z ≈ 15. Using standard arguments including stability, we show that these pre-galactic discs can assemble a significant mass concentration in the inner regions, providing fuel for the formation and initial growth of super-massive black ho...
متن کاملMillion solar mass black holes at high redshift
The existence of quasars at redshift z > 5 indicates that supermassive black holes were present since the very early times. If they grew by accretion, the seeds of mass & 10 M⊙ must have formed at z ∼ 9. These seed black holes may result from the collapse and dissipation of primordial gas during the early stages of galaxy formation. I discuss the effects of magnetic fields on the fragmentation ...
متن کاملRapid growth of high redshift black holes
We discuss a model for the early assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical build-up far up in the dark halo ‘merger tree’. Motivated by the observations of luminous quasars around redshift z ≈ 6 with SMBH masses ≈ 10M⊙, we assess the possibility of an early phase of stable super-critical quasi-spherical accretion in the BHs hosted by me...
متن کاملFeedback Limits Rapid Growth of Seed Black Holes at High Redshift
Seed black holes formed in the collapse of population III stars have been invoked to explain the presence of supermassive black holes at high redshift. It has been suggested that a seed black hole can grow up to 10M⊙ through highly super-Eddington accretion for a period of ∼ 106∼7 yr between redshift z = 20∼ 24. We studied the feedback of radiation pressure, Compton heating and outflow during t...
متن کاملDark matter accretion wakes of high-redshift black holes
Anisotropic emission of gravitational waves during the merger or formation of black holes can lead to the ejection of these black holes from their host galaxies. A recoiled black hole which moves on an almost radial bound orbit outside the virial radius of its central galaxy, in the cold dark matter background, reaches its apapsis in a finite time. The low value of dark matter velocity dispersi...
