Complexity on Small Scales II: Metallicities and Ages in the Leo II Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, J. T. Kleyna +5
We present metallicities and ages for 52 red giants in the remote Galactic dwarf spheroidal (dSph) galaxy Leo II. These stars cover the entire surface area of Leo II and are radial…
Empirical Color Transformations Between SDSS Photometry and Other Photometric Systems
Katrin Jordi, Eva K. Grebel, Karin Ammon
We present empirical color transformations between the Sloan Digital Sky Survey (SDSS) ugriz photometry and Johnson-Cousins UBVRI system and Becker's RGU system, respectively. Owin…
Observed Properties of Dark Matter: dynamical studies of dSph galaxies
G Gilmore, M Wilkinson, J Kleyna +4
The Milky Way satellite dwarf spheroidal (dSph) galaxies are the smallest dark matter dominated systems in the universe. We have underway dynamical studies of the dSph to quantify…
Virgo cluster early-type dwarf galaxies with the Sloan Digital Sky Survey. II. Early-type dwarfs with central star formation
Thorsten Lisker, Katharina Glatt, Pieter Westera +1
Despite the common picture of an early-type dwarf (dE) as a quiescent galaxy with no star formation and little gas, we identify 23 dEs that have blue central colors caused by recen…
The Tully-Fisher Relation and Its Residuals for a Broadly Selected Sample of Galaxies
James Pizagno, Francisco Prada, David H. Weinberg +7
We measure the relation between galaxy luminosity and disk circular velocity (the Tully-Fisher [TF] relation), in the g, r, i, and z-bands, for a broadly selected sample of galaxie…
The Age-Metallicity Relation of the SMC
A. Kayser, E. K. Grebel, D. R. Harbeck +4
The Small Magellanic Cloud (SMC) is the only dwarf galaxy in the Local Group known to have formed and preserved populous star clusters continuously over the past 12 Gyr. These clus…
