Supermassive black holes in scalar field galaxy halos
نویسندگان
چکیده
Ultralight scalar fields provide an interesting alternative to WIMPS as halo dark matter. In this paper we consider the effect of embedding a supermassive black hole within such a halo, and estimate the absorption probability and the accretion rate of dark matter onto the black hole. We show that the accretion rate would be small over the lifetime of a typical halo, and hence that supermassive central black holes can coexist with scalar field halos.

Evolution of supermassive black holes
Supermassive black holes (SMBHs) are nowadays believed to reside in most local galaxies, and the available data show an empirical correlation between bulge luminosity or stellar velocity dispersion and black hole mass, suggesting a single mechanism for assembling black holes and forming spheroids in galaxy halos. The evidence is therefore in favour of a co-evolution between galaxies, black hole...

The formation of supermassive black holes (SMBH) is intimately related to galaxy formation, although precisely how remains a mystery. I speculate that formation of, and feedback from, SMBH may alleviate problems that have arisen in our understanding of the cores of dark halos of galaxies.
متن کاملThe Role of Primordial Kicks on Black Hole Merger Rates
Primordial stars are likely to be very massive ≥ 30 M⊙, form in isolation, and will likely leave black holes as remnants in the centers of their host dark matter halos in the mass range 10 − 10 M⊙. Such early black holes, at redshifts z∼ 10, could be the seed black holes for the many supermassive black holes found in galaxies in the local universe. If they exist, their mergers with nearby super...
متن کاملThe big picture of AGN feedback: Black hole accretion and galaxy evolution in multiwavelength surveys
Large extragalactic surveys allow us to trace, in a statistical sense, how supermassive black holes, their host galaxies, and their dark matter halos evolve together over cosmic time, and so explore the consequences of AGN feedback on galaxy evolution. Recent studies have found significant links between the accretion states of black holes and galaxy stellar populations, local environments, and ...
متن کاملStrong gravitational lensing: Why no central black holes?
We investigate how central black holes (BHs) inhabited in galactic dark halos would affect strong gravitational lensing. The distribution of integral lensing probability with image separations are calculated for quasars of redshift 1.5 by foreground dark matter halos. The mass density of dark halos is taken to be NavarroFrenk-White (NFW) profile such that, when the mass of a halo is less than 1...
