The Globular Cluster Systems around NGC 3311 and NGC 3309
Elizabeth Wehner, Bill Harris, Brad Whitmore +2
We present extensive new photometry in (g',i') of the large globular cluster (GC) system around NGC 3311, the central cD galaxy in the Hydra cluster. Our GMOS data cover a 5.5' fie…
Dissipation and Extra Light in Galactic Nuclei: I. Gas-Rich Merger Remnants
Philip F. Hopkins, Lars Hernquist, Thomas J. Cox +2
We study the origin and properties of 'extra' or 'excess' central light in the surface brightness profiles of gas-rich merger remnants. Combining a large set of hydrodynamical simu…
A Survey of Merger Remnants III: Are Merger Remnants Supported by Rotation or Anisotropy
B. Rothberg, R. D. Joseph
A growing body of observational evidence suggests that the luminosity, photometric shape and amount of rotational or anisotropical support in elliptical galaxies may provide vital…
A Survey of Merger Remnants II: The Emerging Kinematic and Photometric Correlations
B. Rothberg, R. D. Joseph
This paper is the second in a series exploring the properties of 51 {\it optically} selected, single-nuclei merger remnants. Spectroscopic data have been obtained for a sub-sample…
Mid-Infrared and Submillimeter Observations of the Illuminating Source of McNeil's Variable Nebula
Sean M. Andrews, Barry Rothberg, Theodore Simon
We present post-outburst observations of the mid-infrared spectrum and submillimeter continuum of the illuminating source of the newly-discovered McNeil's Nebula in the L1630 regio…
MOND rotation curves for spiral galaxies with Cepheid-based distances
Roelof Bottema, Jose L. G. Pestana, Barry Rothberg +1
Rotation curves for four spiral galaxies with recently determined Cepheid-based distances are reconsidered in terms of modified Newtonian dynamics (MOND). For two of the objects, N…
The Correlation Between Galaxy HI Linewidths and K' Luminosities
B. Rothberg, W. Saunders, R. B. Tully +1
The relationship between galaxy luminosities and rotation rates is studied with total luminosities in the K' band. Extinction problems are essentially eliminated at this band cente…
