Intracluster Planetary Nebulae in Clusters and Groups
John J. Feldmeier, Robin B. Ciardullo, George H. Jacoby +2
We present the results from multiple surveys for intracluster planetary nebulae (IPNe) in nearby galaxy clusters and groups. We find that in the case of clusters, our observations…
Results from a diffuse intracluster light survey
John J. Feldmeier, J. Christopher Mihos, Heather L. Morrison +2
We give an update of our ongoing survey for intracluster light (ICL), in a sample of distant Abell clusters. We find that the amount of intracluster starlight is comparable to that…
Using Intracluster Light to Study Cluster Evolution
John J. Feldmeier, J. Christopher Mihos, Heather L. Morrison +2
We present some early results from our deep imaging survey of galaxy clusters intended to detect and study intracluster light (ICL). From our observations to date, we find that ICL…
HST Observations of the Nuclear Regions of the Toomre Sequence of Merging Galaxies
S. Laine, R. P. van der Marel, T. Boeker +3
We present first results from an HST WFPC2 imaging and STIS spectroscopy program to investigate the structural and star forming properties in the nuclear regions of the Toomre Sequ…
Tidal Tales Two: The Effect of Dark Matter Halos on Tidal Tail Morphology and Kinematics
Chris Mihos, John Dubinski, Lars Hernquist
We examine the effect of different dark matter halo potentials on the morphology and kinematics of tidals tails in a merger model of NGC 7252. We find that models of merging galaxi…
NGC 2442: Tidal Encounters and the Evolution of Spiral Galaxies
Chris Mihos, Greg Bothun
Using imaging Fabry-Perot data, we study the star-forming properties and kinematics of the nearby barred spiral galaxy NGC 2442. The Halpha emission is very localized along the str…
