Exploration of Large Digital Sky Surveys
S. G. Djorgovski, R. J. Brunner, A. A. Mahabal +8
We review some of the scientific opportunities and technical challenges posed by the exploration of the large digital sky surveys, in the context of a Virtual Observatory (VO). The…
Luminosity function of clusters of galaxies
M. Paolillo, S. Andreon, G. Longo +5
The composite galaxy luminosity function (hereafter LF) of 39 Abell clusters of galaxies is derived by computing the statistical excess of galaxy counts in the cluster direction wi…
Modeling of C stars with core/mantle grains: Amorphous carbon + SiC
S. Lorenz-Martins, F. X. de Araujo, S. J. Codina Landaberry +2
A set of 45 dust envelopes of carbon stars has been modeled. Among them, 34 were selected according to their dust envelope class (as suggested by Sloan, Little-Marenin & Price, 199…
Cherenkov radiation in a gravitational wave background
Alexander B. Balakin, Richard Kerner, Jose' P. S. Lemos
A covariant criterion for the Cherenkov radiation emission in the field of a non-linear gravitational wave is considered in the framework of exact integrable models of particle dyn…
The Butcher-Oemler Effect in 295 Clusters: Strong Redshift Evolution and Cluster Richness Dependence
V. E. Margoniner, R. R. de Carvalho, R. R. Gal +1
We examine the Butcher-Oemler effect and its cluster richness dependence in the largest sample studied to date: 295 Abell clusters. We find a strong correlation between cluster ric…
The DEEP Groth Strip Survey X: Number Density and Luminosity Function of Field E/S0 Galaxies at z < 1
Myungshin Im, L. Simard, S. M. Faber +7
We present the luminosity function and color-redshift relation of a magnitude-limited sample of 145 mostly red field E/S0 galaxies at z < 1 from the DEEP Groth Strip Survey (GSS).…
