Towards an Understanding of the Globular Cluster Over--abundance around the Central Giant Elliptical NGC 1399
Markus Kissler-Patig, Carl J. Grillmair, Georges Meylan +3
We investigate the kinematics of a combined sample of 74 globular clusters around NGC 1399. Their high velocity dispersion, increasing with radius, supports their association with…
Detection of Surface Brightness Fluctuations in NGC 4373 Using the Hubble Space Telescope
M. A. Pahre, J. R. Mould, A. Dressler +1
Surface brightness fluctuations (SBF) have been detected for three elliptical galaxies-NGC 3379 in the Leo group, NGC 4406 in the Virgo cluster, and NGC 4373 in the Hydra-Centaurus…
HST Imaging of the Globular Clusters in the Fornax Cluster: Color and Luminosity Distributions
Carl J. Grillmair, Duncan A. Forbes, Jean P. Brodie +1
We examine the luminosity and B-I color distribution of globular clusters for three early-type galaxies in the Fornax cluster using imaging data from the Wide Field/Planetary Camer…
M32+/-1
Tod R. Lauer, S. M. Faber, Edward A. Ajhar +2
WFPC-2 images are used to study the central structure of M31, M32, and M33. The dimmer peak, P2, of the M31 double nucleus is centered on the bulge to 0.1", implying that it is the…
Far-Ultraviolet and Visible Imaging of the Nucleus of M32
A. A. Cole, J. S. Gallagher, J. R. Mould +1
We have imaged the nucleus of M32 at 1600 Angstroms (FUV) and 5500 Angstroms (V) using the Wide-Field/Planetary Camera 2 (WFPC2) aboard HST. We detected the nucleus at 1600 Angstro…
The Luminosity Function and Mass Function in the Galactic Bulge
Jon A. Holtzman, Alan M. Watson, William A. Baum +5
We present deep photometry obtained with the Hubble Space Telescope (HST) in a field in Baade's Window in the Galactic bulge. We derive a luminosity function down to I ~ 24.3, or V…
