We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings on the COSMOS field. We reach a depth for a total cluster flux in the 0.5-2 keV band of…
The stellar content of the COSMOS field as derived from morphological and SED based gtar/galaxy Separation
A. C. Robin, R. M. Rich, H. Aussel +12
We report on the stellar content of the COSMOS two degree field, as derived from a rigorous star/galaxy separation approach developed for using stellar sources to define the point…
A Potential Galaxy Threshing System in the Cosmos Field
S. S. Sasaki, Y. Taniguchi, N. Scoville +26
We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope.…
The VLA-COSMOS Survey: II. Source Catalog of the Large Project
E. Schinnerer, V. Smolcic, C. L. Carilli +11
The VLA-COSMOS large project is described and its scientific objective is discussed. We present a catalog of ~ 3,600 radio sources found in the 2deg^2 COSMOS field at 1.4 GHz. The…
The Cosmic Evolution Survey (COSMOS) -- Overview
N. Scoville, H. Aussel, M. Brusa +19
The Cosmic Evolution Survey (COSMOS) is designed to probe the correlated evolution of galaxies, star formation, active galactic nuclei (AGN) and dark matter (DM) with large-scale s…

zCOSMOS: A Large VLT/VIMOS redshift survey covering 0 < z < 3 in the COSMOS field
S. J. Lilly, O. Le Fevre, A. Renzini +42
zCOSMOS is a large redshift survey that is being undertaken in the COSMOS field using 600 hours of observation with the VIMOS spectrograph on the 8-m VLT. The survey is designed to…
Long-term infrared variability of the UX Ori-type star SV Cep
Attila Juhasz, Timo Prusti, Peter Abraham +1
We investigate the long-term optical-infrared variability of SV Cep, and explain it in the context of an existing UX Ori (UXOR) model. A 25-month monitoring programme was completed…
Draco, a flawless dwarf galaxy
Mathieu Segall, Rodrigo Ibata, Michael Irwin +2
The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass to light ratio and compact size, holds many clues to the nature of the enigmatic dark matter. Here we prese…
