The Group Evolution Multiwavelength Study (GEMS): bimodal luminosity functions in galaxy groups
Trevor A. Miles, Somak Raychaudhury, Duncan A. Forbes +3
We present B and R-band luminosity functions (LF) for a sample of 25 nearby groups of galaxies. We find that the LFs of the groups with low X-ray luminosity (L_X < 10^{41.7} erg/s)…
The Photometric Properties of Isolated Early-Type Galaxies
Fatma M. Reda, Duncan A. Forbes, Michael A. Beasley +2
Isolated galaxies are important since they probe the lowest density regimes inhabited by galaxies. We define a sample of 36 nearby isolated early-type galaxies for further study. O…
Deep Luminosity Functions of Old and Intermediate-Age Globular Clusters in NGC 1316: Evidence for Dynamical Evolution of Second-Generation Globular Clusters
Paul Goudfrooij, Diane Gilmore, Bradley C. Whitmore +1
The Advanced Camera for Surveys on board the Hubble Space Telescope has been used to obtain deep high-resolution images of the giant early-type galaxy NGC 1316 which is an obvious…
The Discovery of New Galaxy Members in the NGC 5044 and NGC 1052 Groups
N. P. F. McKay, C. G. Mundell, S. Brough +6
We present the results of neutral hydrogen (HI) observations of the NGC 5044 and NGC 1052 groups, as part of a GEMS (Group Evolution Multiwavelength Study) investigation into the f…
Direct Evidence for Dynamical Evolution of Luminosity Functions of Globular Cluster Systems: HST/ACS observations of the 3-Gyr-old merger remnant NGC 1316
Paul Goudfrooij
Recent observations of globular clusters (GCs) in intermediate-age (2-4 Gyr old), early-type merger remnants have provided the hitherto `missing link' between young merger remnants…
