Dwarf Galaxies in the Coma Cluster. II. Photometry and Analysis
Jeff Secker, William E. Harris, Julia D. Plummer
We study the dwarf galaxy population in the central ~700 arcmin^2 of the Coma cluster, the majority of which are early-type dwarf elliptical (dE) galaxies. Analysis of the statisti…
Dwarf Galaxies in the Coma Cluster. I. Detection, Measurement and Classification Techniques
Jeff Secker, William E. Harris
Deep B- and R-band CCD images of the central ~700 arcmin^2 of the Coma cluster core have been used to measure the dwarf-galaxy population in Coma. In this paper, we describe a newl…
Photometry and Spectroscopy of Coma Dwarf Ellipticals
Jeff Secker, William E. Harris, Pat Cote +1
We have used deep R- and B-band CCD images (with ~1.2 arcsec seeing) of the central ~700 arcmin^2 of the Coma cluster core (and an associated ~270 arcmin^2 control field) to study…
Unveiling Palomar 2: The Most Obscure Globular Cluster in the Outer Halo
W. E. Harris, P. R. Durrell, G. R. Petitpas +2
We present the first color-magnitude study for Palomar 2, a distant and heavily obscured globular cluster near the Galactic anticenter. Our (V,V-I) color-magnitude diagram (CMD), o…
White Dwarfs in Globular Clusters: HST Observations of M4
Harvey B. Richer, Gregory G. Fahlman, Rodrigo A. Ibata +11
Using WFPC2 on the Hubble Space Telescope, we have isolated a sample of 258 white dwarfs (WDs) in the Galactic globular cluster M4. Fields at three radial distances from the cluste…
