The Dark Energy Camera (DECam)
K. Honscheid, D. L. DePoy
In this paper we describe the Dark Energy Camera (DECam), which will be the primary instrument used in the Dark Energy Survey. DECam will be a 3 sq. deg. mosaic camera mounted at t…
On the distance and reddening of the starburst galaxy IC10
N. Sanna, G. Bono, P. B. Stetson +16
We present deep and accurate optical photometry of the Local Group starburst galaxy IC10. The photometry is based on two sets of images collected with the Advanced Camera for Surve…
Relative distances of Omega Centauri and 47 Tucanae
G. Bono, P. B. Stetson, N. Sanna +18
We present precise optical and near-infrared ground-based photometry of two Globular Clusters (GCs): Omega Cen and 47 Tuc. These photometric catalogs are unbiased in the Red Giant…
The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
CCD Photometry of the Globular Cluster omega Centauri. II. Stellar Populations and Age-Metallicity Relation
S. -C. Rey, Y. -W. Lee, C. Ree +3
We present wide-field and high-precision BV and Ca & Stromgren by photometry of omega Centauri, which represents one of the most extensive photometric surveys to date for this clus…
A Survey for EHB Stars in the Galactic Bulge
Donald M. Terndrup, Deokkeun An, Angela Hansen +3
We present a progress report on an extensive survey to find and characterize all types of blue horizontal-branch stars in the nuclear bulge of the Galaxy. We have obtained wide, sh…
