Planetary Nebulae in Face-On Spiral Galaxies. I. Planetary Nebula Photometry and Distances
Kimberly A. Herrmann, Robin Ciardullo, John J. Feldmeier +1
As the first step to determine disk mass-to-light ratios for normal spiral galaxies, we present the results of an imaging survey for planetary nebulae (PNe) in six nearby, face-on…
The Metallicity Distribution of Intracluster Stars in Virgo
Benjamin F. Williams, Robin Ciardullo, Patrick R. Durrell +11
We have used the Hubble Space Telescope's Advanced Camera for Surveys (ACS) to detect and measure ~5300 stars in a single intracluster field in the Virgo Cluster. By performing F60…
Virgo's Intracluster Globular Clusters as Seen by the Advanced Camera for Surveys
Benjamin F. Williams, Robin Ciardullo, Patrick R. Durrell +11
We report the discovery of 4 candidate intracluster globular clusters (IGCs) in a single deep HST ACS field of the Virgo Cluster. We show that each cluster is roughly spherical, ha…
