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…
Andromeda VIII - a New Tidally Distorted Satellite of M31
Heather Morrison, Paul Harding, Denise Hurley-Keller +1
We report the detection of a new satellite of M31, projected close to M32. And VIII is tidally distorted, with length ~10 kpc and width a few kpc. It contains 5-12 planetary nebula…
M31's Undisturbed Thin Disk of Globular Clusters
H. L. Morrison, P. Harding, K. Perrett +1
We show that there is a subsystem of the M31 globular clusters with THIN DISK kinematics. These clusters span the entire metallicity range of the M31 globular cluster system, in co…
Spectroscopic Discovery of the Supernova 2003dh Associated with GRB 030329
K. Z. Stanek, T. Matheson, P. M. Garnavich +19
We present early observations of the afterglow of the Gamma-Ray Burst (GRB) 030329 and the spectroscopic discovery of its associated supernova SN 2003dh. We obtained spectra of the…
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…
