Metallicities and Radial Velocities of Five Open Clusters Including a New Candidate Member of the Monoceros Stream
Steven R. Warren, Andrew A. Cole
Near infrared spectra of 133 red giant stars from ten Galactic open clusters and two Galactic globular clusters spanning 2.2 dex in metallicity and 11 Gyr in age are presented. We…
The ACS Nearby Galaxy Survey Treasury I. The Star Formation History of the M81 Outer Disk
Benjamin F. Williams, Julianne J. Dalcanton, Anil C. Seth +16
The ACS Nearby Galaxy Survey Treasury (ANGST) is a large Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) treasury program to obtain resolved stellar photometry for a…
The ACS Nearby Galaxy Survey Treasury II. Young Stars and their Relation to Halpha and UV Emission Timescales in the M81 Outer Disk
Stephanie M. Gogarten, Julianne J. Dalcanton, Benjamin F. Williams +11
We have obtained resolved stellar photometry from Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) observations of a field in the outer disk of M81 as part of the ACS…
The ACS LCID Project: RR Lyrae stars as tracers of old population gradients in the isolated dwarf spheroidal galaxy Tucana
Edouard J. Bernard, Carme Gallart, Matteo Monelli +9
We present a study of the radial distribution of RR Lyrae variables, which present a range of photometric and pulsational properties, in the dwarf spheroidal galaxy Tucana. We find…
Leo A: A Late-Blooming Survivor of the Epoch of Reionization in the Local Group
A. A. Cole, E. D. Skillman, E. Tolstoy +8
As part of a major program to use isolated Local Group dwarf galaxies as near-field probes of cosmology, we have obtained deep images of the dwarf irregular galaxy Leo A with the A…
Calcium II Triplet Spectroscopy of LMC Red Giants. I. Abundances and Velocities for a Sample of Populous Clusters
A. J. Grocholski, A. A. Cole, A. Sarajedini +2
Abridged Abstract - Utilizing the FORS2 instrument on the VLT, we have obtained near infrared spectra for more than 200 stars in 28 populous LMC clusters. This cluster sample spans…
