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 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…
The Star Formation History in a SMC field: IAC-star/IAC-pop at work
Noelia E. D. Noel, Antonio Aparicio, Carme Gallart +3
We present a progress report of a project to study the quantitative star formation history (SFH) in different parts of the Small Magellanic Cloud (SMC). We use the information in […
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…
The Araucaria Project. A Wide-Field Photometric Survey for Cepheid Variables in NGC 3109
G. Pietrzynski, W. Gieren, A. Udalski +5
We have obtained mosaic images of NGC 3109 in the V and I bands on 74 nights, spanning approximately one year. From these data, we have conducted an extensive search for Cepheid va…
