Old Massive Globular Clusters and the Stellar Halo of the Dwarf Starburst Galaxy NGC 4449
Jay Strader, Anil C. Seth, Nelson Caldwell
We use Hubble Space Telescope imaging to show that the nearby dwarf starburst galaxy NGC 4449 has an unusual abundance of luminous red star clusters. Joint constraints from integra…
Star Clusters in M 31. IV. A Comparative Analysis of Absorption Line Indices in Old M 31 and Milky Way Clusters
Ricardo P. Schiavon, Nelson Caldwell, Heather Morrison +4
We present absorption line indices measured in the integrated spectra of globular clusters both from the Galaxy and from M 31. Our samples include 41 Galactic globular clusters, an…
Tidal Signatures in the Faintest Milky Way Satellites: The Detailed Properties of Leo V, Pisces II and Canes Venatici II
D. J. Sand, J. Strader, B. Willman +5
We present deep wide-field photometry of three recently discovered faint Milky Way satellites: Leo V, Pisces II, and Canes Venatici II. Our main goals are to study the structure an…
AGES: The AGN and Galaxy Evolution Survey
C. S. Kochanek, D. J. Eisenstein, R. J. Cool +12
The AGN and Galaxy Evolution Survey (AGES) is a redshift survey covering, in its standard fields, 7.7 square degrees of the Bootes field of the NOAO Deep Wide-Field Survey (NDWFS).…
Stellar Clusters in M31 from PHAT: Survey Overview and First Results
L. Clifton Johnson, Anil C. Seth, Julianne J. Dalcanton +9
The Panchromatic Hubble Andromeda Treasury (PHAT) is an on-going Hubble Space Telescope (HST) multi-cycle program that will image one-third of the M31 disk at high resolution, with…
Star Clusters in M31: V. Internal Dynamical Trends: Some Troublesome, Some Reassuring
Jay Strader, Nelson Caldwell, Anil Seth
We present internal velocity dispersions and precise radial velocities for 200 globular clusters (GCs) in M31 that are derived using new high-resolution spectra from MMT/Hectochell…
