The Luminosity Function of Long Gamma-Ray Bursts and their rate at z>6
R. Salvaterra, S. Campana, G. Chincarini +6
We compute the luminosity function (LF) and the formation rate of long gamma ray bursts (GRBs) in three different scenarios: i) GRBs follow the cosmic star formation and their LF i…
Signatures of reionization on Lyman alpha emitters
Pratika Dayal, Andrea Ferrara, Simona Gallerani
We use a semi-analytic model of Lyman alpha emitters (LAEs) to constrain the reionization history. By considering two physically motivated scenarios in which reionization ends eith…
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…
On the Size of HII Regions around High Redshift Quasars
A. Maselli, S. Gallerani, A. Ferrara +1
We investigate the possibility of constraining the ionization state of the intergalactic medium (IGM) close to the end of reionization (z ~ 6) by measuring the size of the HII regi…
