The QSO proximity effect at redshift <z>=2.6 with the FLO approach
V. D'Odorico, M. Bruscoli, F. Saitta +4
We revisit the proximity effect produced by QSOs at redshifts 2.1-3.3 applying the FLO approach (Saitta et al. 2008) to a sample of ~6300 Ly-alpha lines fitted in 21 high resolutio…
The luminosity function of high-redshift QSOs
Fabio Fontanot, Stefano Cristiani, Pierluigi Monaco +5
We measure the luminosity function of QSOs in the redshift range 3.5 < z < 5.2 for the absolute magnitude interval -21 < M_{145} < -28. Suitable criteria are defined to select fain…
The Luminosity Function of high-redshift QSOs - A combined analysis of GOODS and SDSS
F. Fontanot, S. Cristiani, P. Monaco +5
Aims: In this work the luminosity function of QSOs is measured in the redshift range 3.5<z<5.2 for the absolute magnitude interval -21<M_{145}<-28. The determination of the faint e…
Feedback from quasars in star-forming galaxies and the triggering of massive galactic winds
P. Monaco, F. Fontanot
The shining of quasars is a likely trigger of massive galatic winds, able to remove most ISM from a star-forming spheroid. However, the mechanism responsible for the deposition of…
Physical regimes for feedback in galaxy formation
P. Monaco
We present a new (semi-)analytic model for feedback in galaxy formation. The ISM is modeled as a two-phase medium in pressure equilibrium. The remnants of exploding type II SNe per…
The Space Density of High-Redshift QSOs in the GOODS Survey
S. Cristiani, D. M. Alexander, F. Bauer +14
We present a sample of 17 high-redshift (3.5<z<5.2) QSO candidates in the 320 sq.arcmin area of the Great Observatories Origins Deep Survey, selected in the magnitude range 22.45<z…
