The morphology of extremely red objects
G. Moriondo, A. Cimatti, E. Daddi
We present a quantitative study of the morphology of 41 Extremely Red Objects (EROs). The analysis is based on deep otical and near-infrared images from the Hubble Space Telescope…
Searching for high-z field ellipticals: successes and problems
A. Cimatti
The most recent observational results on the search for high redshift field ellipticals are reviewed in the context of galaxy formation scenarios. The perspectives for Large Binocu…
EROs and the formation epoch of field ellipticals
E. Daddi, A. Cimatti, A. Renzini
A comparison is presented between the observed surface density of extremely red objects (EROs) and the densities of red high-z elliptical galaxies predicted by Pure Luminosity Evol…
Sub-mm and X-ray background: two unrelated phenomena?
P. Severgnini, R. Maiolino, M. Salvati +9
Obscured AGNs are thought to contribute a large fraction of the hard X-ray background (2-10 keV), and have also been proposed as the powerhouse of a fraction of the SCUBA sources w…
