Near-UV Merger Signatures in Early-Type Galaxies
Jodie R. Martin, Robert W. O'Connell, J. E. Hibbard
Hierarchical assembly of early-type galaxies (Es and S0s) over an extended period of time will result in mixed-generation stellar populations. Here we look for signatures of compos…
UV Bright Globular Clusters in M87: More Evidence for Super-helium-rich Stellar Populations?
S. Kaviraj, S. T. Sohn, R. W. O'Connell +3
We study the UV and optical properties of 38 massive GCs in M87, imaged using the HST/STIS and WFPC2 instruments. The majority of these GCs appear extremely bright in the FUV - rou…
Ten Years of Super Star Cluster Research
Robert W. O'Connell
This conference demonstrated the tremendous progress that has been made in the last decade in our observational and theoretical understanding of compact, young, massive star cluste…
Super Star Clusters in M82
Robert W. O'Connell
M82 is the nearest starburst galaxy. It contains two large systems of super star clusters, one being spawned today in the active starforming core, and one produced by an earlier st…
Evolved Super Star Clusters in M82
R. de Grijs, R. W. O'Connell, J. S. Gallagher
We present high-resolution optical and near-infrared HST observations of two adjacent regions in the fossil starburst region in M82, B1 and B2. Age estimates date the cluster popul…
Star Formation Triggering Mechanisms in Dwarf Galaxies: The Far-Ultraviolet, H-alpha, and HI Morphology of Holmberg II
S. G. Stewart, M. N. Fanelli, G. G. Byrd +8
Far-UV (FUV), H-alpha, and HI observations of dwarf galaxy Holmberg II are used to trace the interaction between sites of massive star formation and the neutral and ionized compone…
