On the Structural Differences between Disk and Dwarf Galaxies
J. Schombert
Gas-rich dwarf and disk galaxies overlap in numerous physical quantities that make their classification subjective. We report the discovery of a separation between dwarfs and disks…

Cluster Populations in Abell 2125 and 2218
K. Rakos, J. Schombert
We combine new narrow band photometry with archival WFPC2 data for A2218 (=0.18) and A2125 (=0.25), two clusters with intermediate redshifts but very different cluster proper…

Age and Metallicity Estimations in Old Stellar Populations from Stromgren Photometry
K. Rakos, J. Schombert, A. Odell
We present a new technique to determine age and metallicity of old stellar populations (globular clusters and elliptical galaxies) using an iterative principal component analysis o…
