Black Holes and Hosts of Active Galactic Nuclei: I. the Black Hole-bulge Relation Revisited
Massive Black Holes detected by in the centers of many nearby galaxies show an approximately linear relation with the luminosity of the host bulge, inferring the black hole has a mass of 0.001-0.002 of the bulge. Previous work suggested that black holes of active (Seyfert 1) galaxies follow a similar relation, but apparently with a significantly lower value of MBH/Mbulge (Wandel 1999). New data...
متن کاملBlack Holes of Active and Quiescent Galaxies: I. the Black Hole-bulge Relation Revisited
Massive Black Holes detected in the centers of many nearby galaxies show an approximately linear relation with the luminosity of the host bulge, with the black hole mass being 0.001-0.002 of the bulge mass. Previous work suggested that black holes of active (Seyfert 1) galaxies follow a similar relation, but apparently with a significantly lower value of MBH/Mbulge (Wandel 1999). New data show ...
متن کاملRadiatively Driven Jets around Black Holes
The hot, puffed up, post-shock region of an advective disc is the source of high energy photons and also the jets and outflows. We study the relativistic equations of motion of jets as these high energy photons interact with them. We show that the much discussed terminal velocity of jets depends on the comparative value of radiative energy density, flux and the radiative pressure. We show that ...
متن کاملThe 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 کاملOn the Fueling of Massive Black Holes and the Properties of Their Host Spheroids
We study the relation between nuclear massive black holes and their host spheroid gravitational potential. Using simple models, we analyze how gas is expected to be transported in the nuclear regions of galaxies. When we couple it with the expected gas lifetime given by the Kennicutt-Schmidt Law, this naturally leads to the ‘MBH Mvirial’ and ‘MBH σ’ relations. Subject headings: quasars: general...
