An ESO/VLT survey of NIR (Z<=25) selected galaxies at redshifts 4.5<z<6: constraining the cosmic star formation rate near the reionization epoch
A. Fontana, F. Poli, N. Menci +4
We present the results of a VLT and HST imaging survey aimed at the identification of 4.5<z<6 galaxies. In the VLT data, a set of broad and intermediate band filters has been used…
The dusty environment of Quasars. Far-IR properties of Optical Quasars
Paola Andreani, Stefano Cristiani, Andrea Grazian +2
We present the ISO far-IR photometry of a complete sub-sample of optically selected bright quasars belonging to two complete surveys selected through multicolour (U,B,V,R,I) techni…
The All-Sky Asiago-ESO/RASS QSO Survey: Clustering and Luminosity Function
A. Grazian, S. Cristiani, A. Omizzolo
The AERQS is a project aimed at the construction of an all-sky statistically well-defined sample of local (z < 0.3) and bright (R < 15.5) QSOs. Present uncertainties on the theoret…
The Asiago-ESO/RASS QSO Survey II. The Southern Sample
A. Grazian, A. Omizzolo, C. Corbally +3
This is the second paper of a series describing the Asiago-ESO/RASS QSO survey, a project aimed at the construction of an all-sky statistically well-defined sample of very bright Q…
The K20 survey. IV. The redshift distribution of Ks<20 galaxies: a test of galaxy formation models
A. Cimatti, L. Pozzetti, M. Mignoli +11
We present the redshift distribution of a complete sample of 480 galaxies with Ks<20 distributed over two independent fields covering a total area of 52 arcmin^2. The redshift comp…
The K20 survey. III. Photometric and spectroscopic properties of the sample
A. Cimatti, M. Mignoli, E. Daddi +12
The K20 survey is an ESO VLT optical and near-infrared spectroscopic survey aimed at obtaining spectral information and redshifts of a complete sample of about 550 objects to K_s\l…
