Scientific paper

We present Hobby-Eberly Telescope (HET) observations for galaxies at 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 and tests of binarity. The results are compared with the large velocity dispersions expected from the large black hole masses found in some QSOs. Galaxies with the largest confirmed velocity dispersions will provide targets to search for the largest black holes.
