WFPC2 Observations of the Cooling Flow Elliptical in Abell 1795
Jason Pinkney, Jon Holtzman, Chris Garasi +3
We present WFPC2 images of the core of the cooling flow cD galaxy in Abell 1795. An irregular, asymmetric dust lane extends 7 \h75 kpc in projection to the north-northwest. The dus…
Low-Mass AGN and Their Relation to the Fundamental Plane of Black Hole Accretion
Kayhan Gultekin, Edward M. Cackett, Ashley L. King +2
We put active galactic nuclei (AGNs) with low-mass black holes on the fundamental plane of black hole accretion---the plane that relates X-ray emission, radio emission, and mass of…
A Quintet of Black Hole Mass Determinations
Kayhan Gultekin, Douglas O. Richstone, Karl Gebhardt +11
We report five new measurements of central black hole masses based on STIS and WFPC2 observations with the Hubble Space Telescope and on axisymmetric, three-integral, Schwarzschild…
Substructure in clusters containing wide-angle tailed radio galaxies. I. New redshifts
Jason Pinkney, Jack O. Burns, Michael J. Ledlow +2
We present new redshifts and positions for 635 galaxies in nine rich clusters containing Wide-Angle Tailed (WAT) radio galaxies. Combined with existing data, we now have a sample o…
The Black Hole Mass and Photometric Components of NGC 4826
Kayhan Gültekin, Karl Gebhardt, John Kormendy +6
We present IR photometry and HST imaging and spectroscopy of Sab galaxy NGC 4826. Schwarzschild dynamical modeling is used to measure its central black hole mass . Photometric d…
Galaxies with a Central Minimum in Stellar Luminosity Density
Tod R. Lauer, Karl Gebhardt, Douglas Richstone +15
We used HST WFPC2 images to identify six early-type galaxies with surface- brightness profiles that decrease inward over a limited range of radii near their centers. The implied lu…
