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 VLT observations of the HDF-S NICMOS field: photometric catalog and high redshift galaxy candidates
A. Fontana, S. D'Odorico, R. Fosbury +6
We present the deep UBVRI observations of the HDF-S NICMOS field obtained as part of the Science Verification of the VLT Unit 1 telescope. The images have been used to construct ob…
The NTT Susi Deep Field
S. Arnouts, S. D'Odorico, S. Cristiani +3
We present a deep BVrI multicolor catalog of galaxies in a 5.62 sq.arcmin field 80 arcsec south of the high redshift (z=4.7) quasar BR 1202-0725, derived from observations with the…
Clustering of Absorbers
S. Cristiani, S. D'Odorico, V. D'Odorico +4
The observed clustering of Lyman- lines is reviewed and compared with the clustering of CIV systems. We argue that a continuity of properties exists between Lyman- and metal…
The UV Background and the Lyman alpha Clouds at High Redshift
E. Giallongo, S. Cristiani, S. D'Odorico +2
The estimate of the ionizing UV background through the proximity effect analysis is discussed. Taking into account the correct bending of the column density distribution which appe…
Search for Galaxies at z>4 from a Deep Multicolor Survey
E. Giallongo, S. Charlot, S. Cristiani +2
We present deep BVrI multicolor photometry in the field of the quasar BR1202-07 (z_{em}=4.694) aimed at selecting field galaxies at z>4. We compare the observed colors of the galax…
