In search of the largest velocity dispersion galaxies.

Abstract (from CDS):

We present Hobby-Eberly Telescope (HET) observations for galaxies at redshift z<0.3 from the Sloan Digital Sky Survey (SDSS) showing large velocity dispersions while appearing to be single galaxies in HST images. The high signal-to-noise HET spectra provide more definitive velocity dispersions. The maximum velocity dispersion we find is σ*=444 km/s. Emission-line widths in QSOs indicate that black holes can exist with masses Mø exceeding 5 billion M☉, implying σ*>500 km/s by the local Mø-σ*relationship. This suggests either that QSO black hole masses are overestimated or that the black hole-bulge relationship changes at high black hole mass. The latter option is consistent with evidence that the increase in σ* with luminosity levels off for the brightest elliptical galaxies.
