Narrow Band Continuum Colors of Distant Cluster Populations
J. Schombert, K. Rakos
In this poster, we present new results on narrow band photometry for A2218 (=0.18) and A2125 (=0.25), two clusters with similar redshifts, but very different cluster properti…

Global Metallicities From Globulars Through To Elliptical Galaxies
K. Rakos, J. Schombert, A. Odell
We present narrow band data on dwarf ellipticals in nearby (Virgo, Fornax) and intermediate redshift clusters (A2125, A2218) in order to study their mean age and metallicities. In…

Color Evolution from z=0 to z=1
Karl Rakos, James Schombert
Rest frame Stromgren photometry (3500A, 4100A, 4750A and 5500A) is presented for 509 galaxies in 17 rich clusters between z=0 and z=1 as a test of color evolution. Our observations…
