Cluster galaxies: contribution to the arc statistics
Massimo Meneghetti, Micol Bolzonella, Matthias Bartelmann +2
We present the results of a set of numerical simulations aiming at evaluating the effects of cluster galaxies on the arc statistics. At this goal we use nine different galaxy clust…
Interpreting the optical data of the Hubble Deep Field South: colors, morphological number counts and photometric redshifts
M. Volonteri, P. Saracco, G. Chincarini +1
We present an analysis of the optical data of the Hubble Deep Field South. We derive F300W(AB), F450W(AB), F606W(AB) and F814W(AB) number counts for galaxies in all four bands. The…
Photometric Redshifts and Gravitational Telescopes
R. Pello, M. Bolzonella, J. F. Le Borgne +8
We review the use of photometric redshifts in the particular context of Gravitational Telescopes. We discuss on the possible application of such a technique to the study of both th…
Photometric Redshifts based on standard SED fitting procedures
Micol Bolzonella, Joan-Marc Miralles, Roser Pello'
In this paper we study the accuracy of photometric redshifts computed through a standard SED fitting procedure, where SEDs are obtained from broad-band photometry. We present our p…
