Tracing the evolution of massive galaxies up to z \sim 3
M. Longhetti, P. Saracco, S. Cristiani +4
A census of massive galaxies at redshift increasingly higher than 1 may provide strong constraints on the history of mass assembly and of star formation. Here we report on t…
The TESIS project: Are type 2 QSO hidden in X-ray emitting EROs?
P. Severgnini, R. Della Ceca, V. Braito +8
Here we present the results obtained from the analysis of 75 ksec of XMM-Newton observations of a sample of EROs selected from one MUNICS field (K'<19.5 mag). We find 6 EROs with a…
The TESIS project: revealing massive early-type galaxies at z>1
P. Saracco, M. Longhetti, P. Severgnini +8
We present the preliminary results of an on-going near-IR low resolution spectroscopic follow-up of a complete sample of 30 bright (K'<18.5) EROs selected over 360 arcmin^2 from th…
Star Formation History of Early-Type Galaxies in Low Density Environments V. Blue line-strength indices for the nuclear region
M. Longhetti, A. Bressan, C. Chiosi +1
We analyze the star formation properties of a sample of 21 shell galaxies and 30 early-type galaxies members of interacting pairs, located in low density environments (Longhetti et…
