The Ages of Dwarf Ellipticals
K. Rakos, J. Schombert
We present narrow band photometry of 91 dwarf ellipticals in the Coma and Fornax clusters taken through the Stromgren (uvby) filter system. Dividing the sample by dwarf morphology…
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…
Stroemgren uvby photometry of the open clusters NGC 6192 and NGC 6451
E. Paunzen, H. M. Maitzen, K. D. Rakos +1
We have investigated the two open clusters NGC 6192 and NGC 6451 for which widely different reddening values and thus ages and distances can be found in the literature via Stroemgr…
