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…
Photometric redshifts with the Multilayer Perceptron Neural Network: application to the HDF-S and SDSS
E. Vanzella, S. Cristiani, A. Fontana +8
We present a technique for the estimation of photometric redshifts based on feed-forward neural networks. The Multilayer Perceptron (MLP) Artificial Neural Network is used to predi…
The Chandra Deep Field South: Optical Spectroscopy I
G. P. Szokoly, J. Bergeron, G. Hasinger +15
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field South (CDFS). 288 possible counterparts…
Deep near-infrared imaging of RDCS J1252.9-2927 at z=1.237: The colour-magnitude diagram
C. Lidman, P. Rosati, R. Demarco +4
We present deep SofI and ISAAC near-infrared imaging data of the X-ray luminous galaxy cluster RDCS J1252.9-2927. The ISAAC data were taken at the ESO Very Large Telescope under ve…
High-z massive galaxies in the HDF-South
P. Saracco, M. Longhetti, E. Giallongo +6
[abr] We report the analysis of three galaxies selected in the Hubble Deep Field South at Ks<22 on the basis of their unusually red near-IR color J-K>3. We have used population syn…
Chandra and XMM-Newton Observations of RDCS1252.9-2927, A Massive Cluster at z=1.24
P. Rosati, P. Tozzi, S. Ettori +10
We present deep Chandra and XMM obervations of the galaxy cluster RDCS1252.9-2927, which was selected from the ROSAT Deep Cluster Survey (RDCS) and confirmed by extensive spectrosc…
