Connecting Transitions in Galaxy Properties to Refueling
Sheila J. Kannappan, David V. Stark, Kathleen D. Eckert +12
We relate transitions in galaxy structure and gas content to refueling, here defined to include both the external gas accretion and the internal gas processing needed to renew rese…
Gemini/GMOS Imaging of Globular Cluster Systems in Five Early-type Galaxies
Favio R. Faifer, Juan C. Forte, Mark A. Norris +7
This paper presents deep high quality photometry of globular cluster (GC) systems belonging to five early-type galaxies covering a range of mass and environment. Photometric data w…
The Ubiquity and Dual Nature of Ultra Compact Dwarfs
Mark A. Norris, Sheila J. Kannappan
We present the discovery of several Ultra Compact Dwarfs (UCDs) located in field/group environments. Examination of these objects, plus literature objects, confirms the existence o…
UCDs as Probes of the Major and Minor Merger Histories of Galaxies
Mark A. Norris, Sheila J. Kannappan
Two competing theories posit that Ultra Compact Dwarfs (UCDs) form either as the stripped nuclei of dwarf galaxies or as giant globular clusters (GGCs) associated with the largest…
