HAWK-I imaging of the X-ray luminous galaxy cluster XMMU J2235.3-2557: The red sequence at z=1.39
C. Lidman, P. Rosati, M. Tanaka +7
We use HAWK-I, the recently-commissioned near-IR imager on Yepun (VLT-UT4), to obtain wide-field, high-resolution images of the X-ray luminous galaxy cluster XMMU J2235.3-2557 in t…
Star formation histories of early-type galaxies at z = 1.2 in cluster and field environments
R. Gobat, P. Rosati, V. Strazzullo +3
We derive the star formation histories of early-type galaxies at z = 1.2 in both low and high density environments. To this purpose, we compare the co-added spectroscopic and 8-9 b…
The Red Sequence of High-Redshift Clusters: a Comparison with Cosmological Galaxy Formation Models
N. Menci, P. Rosati, R. Gobat +4
We compare the results from a semi-analytic model of galaxy formation with spectro-photometric observations of distant galaxy clusters observed in the range 0.8< z< 1.3. We investi…
Comparing dynamical and photometric-stellar masses of early-type galaxies at z ~ 1
A. Rettura, P. Rosati, V. Strazzullo +14
The purpose of this study is to explore the relationship between galaxy stellar masses, based on multiwavelength photometry spectral template fitting and dynamical masses based on…
Evolution of the Color-Magnitude Relation in High-Redshift Clusters: Blue Early-Type Galaxies and Red Pairs in RDCS J0910+5422
S. Mei, J. P. Blakeslee, S. A. Stanford +17
The color-magnitude relation has been determined for the RDCS J0910+5422 cluster of galaxies at redshift z = 1.106. Cluster members were selected from HST ACS images, combined with…
Morphology of low-redshift compact galaxy clusters I. Shapes and radial profiles
V. Strazzullo, M. Paolillo, G. Longo +4
The morphology of clusters of galaxies may be described with a set of parameters which contain information about the formation and evolutionary history of these systems. In this pa…
