The pre-processing of subhaloes in SDSS groups and clusters
Annie Hou, Laura C. Parker, William E. Harris
We investigate pre-processing using the observed quenched fraction of group and cluster galaxies in the Yang et al. (2007) SDSS-DR7 group catalogue in the redshift range of 0.01 <…
Star Formation and Environmental Quenching of GEEC2 Group Galaxies at z~1
Angus Mok, Michael L. Balogh, Sean L. McGee +7
We present new analysis from the GEEC2 spectroscopic survey of galaxy groups at . Our previous work revealed an intermediate population between the star-forming and quiesc…
Do group dynamics play a role in the evolution of member galaxies?
Annie Hou, Laura C. Parker, Michael L. Balogh +8
We examine galaxy groups from the present epoch to z = 1 to explore the impact of group dynamics on galaxy evolution. We use group catalagues from the Sloan Digital Sky Survey (SDS…
Efficient satellite quenching at z~1 from the GEEC2 spectroscopic survey of galaxy groups
Angus Mok, Michael L. Balogh, Sean L. McGee +9
We present deep GMOS-S spectroscopy for 11 galaxy groups at 0.8<z<1.0, for galaxies with r_{AB}<24.75. Our sample is highly complete (>66%) for eight of the eleven groups. Using an…
Exploring the Diversity of Groups at 0.1<z<0.8 with X-ray and Optically Selected Samples
Jennifer L. Connelly, David J. Wilman, Alexis Finoguenov +8
We present the global group properties of two samples of galaxy groups containing 39 high quality X-ray selected systems and 38 optically (spectroscopically) selected systems in co…
Substructure in the Most Massive GEEC Groups: Field-like Populations in Dynamically Active Groups
Annie Hou, Laura C. Parker, David J. Wilman +6
The presence of substructure in galaxy groups and clusters is believed to be a sign of recent galaxy accretion and can be used not only to probe the assembly history of these struc…
New g'r'i'z' Photometry of the NGC 5128 Globular Cluster System
B. Sinnott, A. Hou, R. Anderson +2
We present new photometry for 323 of the globular clusters in NGC 5128 (Centaurus A), measured for the first time in the filter system. The color indices are calibrated…
Statistical Tools for Classifying Galaxy Group Dynamics
Annie Hou, Laura C. Parker, William E. Harris +1
The dynamical state of galaxy groups at intermediate redshifts can provide information about the growth of structure in the universe. We examine three goodness-of-fit tests, the An…
