The evolution of field early-type galaxies to z~0.7
T. Treu, M. Stiavelli, S. Casertano +2
We have measured the Fundamental Plane (FP) parameters for a sample of 30 field early-type galaxies (E/S0) in the redshift range 0.1<z<0.66. We find that: i) the FP is defined and…
Near-infrared Spectroscopy and HST Imaging of a Dusty Starburst ERO
Graham P. Smith, Tommaso Treu, Richard Ellis +3
We present near-IR spectroscopy and HST imaging of EROJ164023, an Extremely Red Object (ERO) with R-K=5.9 at z=1.05. EROJ164023 is a disk galaxy, with an optical/IR spectral energy…
The properties of field elliptical galaxies at intermediate redshift. III: the Fundamental Plane and the evolution of stellar populations from z~0.4 to z=0
T. Treu, M. Stiavelli, G. Bertin +2
We report on the study of a sample of 25 field early-type galaxies, in the redshift range z~0.1-0.5, selected on the basis of colours and morphology from the HST-MDS. Field early-t…
Lyman alpha emitters with red colors at z~=2.4
M. Stiavelli, C. Scarlata, N. Panagia +3
We have carried out a search for Lyman alpha emission from galaxies at z~=2.4 over a field of 1200 sq. arcmin using the CFH12K camera at the CFHT and a custom medium band filter. T…
The properties of field elliptical galaxies at intermediate redshift. II: photometry and spectroscopy of an HST selected sample
T. Treu, M. Stiavelli, P. Møller +2
A sample of field early-type galaxies (E/S0) at intermediate redshift () is selected, based on morphology and colours from HST-WFPC2 parallel images. Photometric stru…
