Probing the Large Scale Structure with QSOs and radio-galaxies
S. Cristiani
QSOs and radio-galaxies, together with the CMB, ``normal'' galaxies and clusters, represent the main source of information about the origin and evolution of the Large Scale Structu…
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…
The luminosity function and clustering evolution of Quasars
S. Cristiani, F. La Franca, P. Andreani
Recent results have questioned the description of the QSO luminosity function in terms of a pure luminosity evolution and call for a luminosity dependent luminosity evolution. Meas…
ERRATUM on The QSO evolution derived from the HBQS and other complete QSO surveys
F. La Franca, S. Cristiani
An ESO Key programme dedicated to an Homogeneous Bright QSO Survey (HBQS) has been completed. 327 QSOs (Mb<-23, 0.3<z<2.2) have been selected over 555 deg^2 with 15<B<18.75. For B<…
The evolution of the clustering of QSOs
F. La Franca, P. Andreani, S. Cristiani
The evolution of QSO clustering is investigated with a new sample of 388 QSOs with 0.3<z<2.2, B<20.5 and M_B<-23. Evidence is found for an increase of the clustering amplitude with…
