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…
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…
