Interpreting the Transmission Windows of Distant Quasars
A. Maselli, A. Ferrara, S. Gallerani
We propose the Apparent Shrinking Criterion (ASC) to interpret the spatial extent, R_w, of transmitted flux windows in the absorption spectra of high-z quasars. The ASC can discrim…
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…
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…
