The evolution of the galaxy B-band rest-frame morphology to z~2: new clues from the K20/GOODS sample
P. Cassata, A. Cimatti, A. Franceschini +7
We present a detailed analysis of the evolution of the rest-frame B-band morphology of K-selected galaxies with 0 < z < 2.5. This work is based on the K20 spectroscopic sample (Ks<…
XMM-Newton observations of Extremely Red Objects and the link with luminous, X-ray obscured Quasars
M. Brusa, A. Comastri, E. Daddi +8
We present the results of a deep (about 80 ks) XMM-Newton survey of the largest sample of near-infrared selected Extremely Red Objects (R-K>5) available to date to K_S< 19.2. At th…
A new photometric technique for the joint selection of star-forming and passive galaxies at 1.4<z<2.5
E. Daddi, A. Cimatti, A. Renzini +5
A simple two color selection based on B-, z-, and K- band photometry is proposed for culling galaxies at 1.4<z<2.5 in K-selected samples and classifying them as star-forming or pas…
Old Galaxies in the Young Universe
A. Cimatti, E. Daddi, A. Renzini +8
More than half of all stars in the local Universe are found in massive spheroidal galaxies, which are characterized by old stellar populations with little or no current star format…
The K20 survey. VI. The Distribution of the Stellar Masses in Galaxies up to z~2
A. Fontana, L. Pozzetti, I. Donnarumma +14
We present a detailed analysis of the stellar mass content of galaxies up to z=2.5 in the K20 galaxy sample, that has a 92% spectroscopic completeness and a complete m…
The HELLAS2XMM survey: VI. X-ray absorption in the 1dfAGN sample through a spectral analysis
G. C. Perola, S. Puccetti, F. Fiore +13
The spectroscopic analysis of 117 serendipitous sources in the HELLAS2XMM 1df (1 degree field) survey is described. Of these, 106 sources, of which 86% have a spectroscopic redshif…
