Spectral Energy Distributions of QSOs at z>5: common AGN-heated dust and occasionally strong star-formation
C. Leipski, K. Meisenheimer, F. Walter +7
We present spectral energy distributions (SEDs) of 69 QSOs at z>5, covering a rest frame wavelength range of 0.1mu to ~80mu, and centered on new Spitzer and Herschel observations.…
Constraining cosmic reionization with quasar, gamma ray burst, and Lya emitter observations
S. Gallerani, A. Ferrara, T. R. Choudhury +3
We investigate the cosmic reionization history by comparing semi-analytical models of the Lya forest with observations of high-z quasars and gamma ray bursts absorption spectra. In…
Was the Universe neutral beyond redshift six?
S. Gallerani, A. Ferrara, X. Fan +2
We provide measurements of the neutral hydrogen fraction xHI at z~6, by comparing semi-analytical models of the Lyalpha forest with observations of high-z quasars and Gamma Ray Bur…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
Glimpsing through the high redshift neutral hydrogen fog
S. Gallerani, A. Ferrara, X. Fan +1
We analyze the transmitted flux in a sample of 17 QSOs spectra at 5.74<zem<6.42 to obtain tighter constraints on the volume-averaged neutral hydrogen fraction, xHI, at z~6. We stud…
Spitzer Observations of High Redshift QSOs
D. C. Hines, O. Krause, G. H. Rieke +3
We have observed 13 z >= 4.5 QSOs using the Multiband Imaging Photometer for Spitzer, nine of which were also observed with the Infrared Array Camera. The observations probe rest w…
