On the minimum mass of reionization sources
T. Roy Choudhury, A. Ferrara, S. Gallerani
By means of carefully calibrated semi-analytical reionization models, we estimate the minimum mass of star-forming haloes required to match the current data. Models which do not in…

Testing Reionization with Gamma Ray Burst Absorption Spectra
S. Gallerani, R. Salvaterra, A. Ferrara +1
We propose to study cosmic reionization using absorption line spectra of high-redshift Gamma Ray Burst (GRB) afterglows. We show that the statistics of the dark portions (gaps) in…

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…
