The Evolution of the Mbh-σ Relation
We examine the evolution of the black hole mass stellar velocity dispersion (MBH−σ) relation over cosmic time using simulations of galaxy mergers that include feedback from supermassive black hole growth. Our calculations have been shown to reproduce the power-law scaling of the local, redshift zero MBH−σ relation and yield the observed normalization for an appropriate choice of the feedback ef...
متن کاملFundamental Planes, and the Barless Mbh-σ Relation, for Supermassive Black Holes
The residuals about the standard Mbh-σ relation correlate with the effective radius, absolute magnitude, and Sérsic index of the host bulge. Although, it is noted here that the elliptical galaxies do not partake in such correlations. Moreover, it is revealed that barred galaxies (with their relatively small, faint, and low stellar concentration bulges) can deviate from the Mbh-σ relation by δ l...
متن کاملDynamical Growth of Black Holes and the MBH −σ Relation
This poster discusses a possible explanation for the relationship between the mass of the central supermassive black hole and the velocity dispersion in the bulge of the host galaxy. We suppose that the black hole and the dark matter halo are forming simultaneously as matter falls in, and a self-similar system then exists in which the mass and the velocities of the system evolve as power-law fu...
متن کاملThe Mbh −σ∗ Relation in Local Active Galaxies
We examine whether active galaxies obey the same relation between black hole mass and stellar velocity dispersion as inactive systems, using the largest published sample of velocity dispersions for active nuclei to date. The combination of 56 original measurements with objects from the literature not only increases the sample from the 15 considered previously to 88 objects, but allows us to cov...
متن کاملMBH - σ relation in SDSS flat-spectrum radio quasars
The relationship between the black hole mass and velocity dispersion indicated with [O III] line width is investigated for a sample of 87 flat-spectrum radio quasars (FSRQs) selected from SDSS DR3 quasar catalogue. We found the Mbh − σ[OIII] relation is deviated from Tremaine et al. relation for nearby inactive galaxies, with a larger black hole mass at given velocity dispersion. There is no st...
