Globular Cluster Scale Sizes in Giant Galaxies: The Case of M87 and the Role of Orbital Anisotropy and Tidal Filling
Jeremy J. Webb, Alison Sills, William E. Harris
We present new Hubble Space Telescope imaging of the outer regions of M87 in order to study its globular cluster (GC) population out to large galactocentric distances. We discuss p…
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…
Unearthing Foundations of a Cosmic Cathedral: Searching the Stars for M33's Halo
Robert Cockcroft, Alan W. McConnachie, William E. Harris +9
We use data from the Pan-Andromeda Archaeological Survey (PAndAS) to search for evidence of an extended halo component belonging to M33 (the Triangulum Galaxy). We identify a popul…
The Size Difference Between Red And Blue Globular Clusters Is NOT Due To Projection Effects
Jeremy J. Webb, William E. Harris, Alison Sills
Metal-rich (red) globular clusters in massive galaxies are, on average, smaller than metal-poor (blue) globular clusters. One of the possible explanations for this phenomenon is th…
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…
The Observational and Theoretical Tidal Radii of Globular Clusters in M87
Jeremy J. Webb, Alison Sills, William E. Harris
Globular clusters have linear sizes (tidal radii) which theory tells us are determined by their masses and by the gravitational potential of their host galaxy. To explore the relat…
