Compact High-Redshift Galaxies Are the Cores of the Most Massive Present-Day Spheroids (2009)

Hopkins, Philip F., Bundy, Kevin, Murray, Norman, Quataert, Eliot, Lauer, Tod, Ma, Chung-Pei

Observations suggest that effective radii of high-z massive spheroids are as much as a factor ~6 smaller than low-z galaxies of comparable mass. Given the apparent absence of low-z counterparts, this...

Calibration of the Extragalactic Distance Scale: Tip of the Red Giant Branch Distance to NGC 3379 (M105) in the Leo I Group (2004)

Sakai, Shoko, Madore, Barry F., Freedman, Wendy L., Lauer, Tod

We report the unambiguous detection of individually resolved stars in the elliptical galaxy NGC 3379, a luminous member of the Leo I Group.

Kinematics of Ten Early-Type Galaxies from HST and Ground-Based Spectroscopy (2003)

Pinkney, Jason, Gebhardt, Karl, Bender, Ralf, Bower, Gary, Dressler, Alan, Faber, S. M., ...

We present stellar kinematics for a sample of 10 early-type galaxies observed using the STIS aboard the Hubble Space Telescope, and the Modular Spectrograph on the MDM Observatory 2.4-m telescope....

Black Hole Mass Estimates from Reverberation Mapping and from Spatially Resolved Kinematics (2000)

Gebhardt, Karl, Kormendy, John, Ho, Luis, Bender, Ralf, Bower, Gary, Dressler, Alan, ...

Black hole (BH) masses that have been measured by reverberation mapping in active galaxies fall significantly below the correlation between bulge luminosity and BH mass determined from spatially...

Axisymmetric, 3-Integral Models of Galaxies: A Massive Black Hole in NGC3379 (1999)

Gebhardt, Karl, Richstone, Douglas, Kormendy, John, Lauer, Tod, Ajhar, Edward, Bender, Ralf, ...

We fit axisymmetric 3-integral dynamical models to NGC3379 using the line-of-sight velocity distribution obtained from HST/FOS spectra of the galaxy center and ground-based long-slit spectroscopy...

The Demography of Massive Dark Objects in Galaxy Centres (1997)

Magorrian, John, Tremaine, Scott, Richstone, Douglas, Bender, Ralf, Bower, Gary, Dressler, Alan, ...

We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with a...

Spectroscopic Evidence for a Supermassive Black Hole in NGC 4486B (1997)

Kormendy, John, Bender, Ralf, Magorrian, John, Tremaine, Scott, Gebhardt, Karl, Richstone, Douglas, ...

The stellar kinematics of the dwarf elliptical galaxy NGC 4486B have been measured in seeing sigma_* = .22 arcsec with the Canada-France-Hawaii Telescope. Lauer et al. 1996, ApJ, 471, L79 have shown...

The Centers of Early-Type Galaxies with HST III: Non-Parametric Recovery of Stellar Luminosity Distributions (1996)

Gebhardt, Karl, Richstone, Douglas, Ajhar, Edward, Lauer, Tod, Byun, Yong-Ik, Kormendy, John, ...

We have non-parametrically determined the luminosity density profiles and their logarithmic slopes for 42 early-type galaxies observed with HST. Assuming that the isodensity contours are spheroidal,...
