Reflections of Cluster Assembly in the Stellar Populations and Dynamics of Member Galaxies
Sean M. Moran, Richard S. Ellis, Tommaso Treu +1
We combine optical (HST) and UV (GALEX) imaging of two intermediate redshift galaxy clusters with spectroscopy of member galaxies, to study the relation between the formation histo…
Hidden activity in high-redshift spheroidal galaxies from mid-infrared and X-ray observations in the GOODS-North field
G. Rodighiero, C. Gruppioni, F. Civano +6
We exploit very deep mid-IR (MIR) and X-ray observations by Spitzer and Chandra in the GOODS North to identify signs of hidden (either starburst or AGN) activity in spheroidal gala…
The Formation of Early-Type Galaxies: Observations to z=1
T. Treu
How does the number density of early-type galaxies (E+S0) evolve with redshift? What are their star formation histories? Do their mass density profile and other structural properti…
The Morphology of Extremely Red Objects
M. Stiavelli, T. Treu
We briefly discuss our survey of Extremely Red Objects (EROs) with HST/NICMOS and deep ground-based images and summarize its results. We use the high-resolution NICMOS images to su…
The Fundamental Plane of field early-type galaxies at intermediate redshift
T. Treu, M. Stiavelli, S. Casertano +2
We present preliminary results on the evolution of the stellar populations of field early-type galaxies (E/S0) from z=0.4 to z=0. The diagnostic tool used in this study is the Fund…
An Extremely Red r^{1/4} Galaxy in the Test Image of the Hubble Deep Field South
T. Treu, M. Stiavelli, A. R. Walker +14
We report the serendipitous discovery of an extremely red object in the Hubble Deep Field South (HDFS) Test NICMOS (Near Infrared Camera and Multi Object Spectrograph) field of vie…
