Afterglow spectrum of a gamma-ray burst with the highest known redshift z=6.295
N. Kawai, G. Kosugi, K. Aoki +25
Gamma-ray bursts (GRBs) and their afterglows have been proposed as an excellent probe to study the evolution of cosmic star formation, the reionization of the intergalactic medium,…
Implications for the Cosmic Reionization from the Optical Afterglow Spectrum of the Gamma-Ray Burst 050904 at z = 6.3
Tomonori Totani, Nobuyuki Kawai, George Kosugi +5
The gamma-ray burst (GRB) 050904 at z = 6.3 provides the first opportunity of probing the intergalactic medium (IGM) by GRBs at the epoch of the reionization. Here we present a spe…
Deep Spectroscopic Survey of Lyman Break Galaxies at z~5
M. Ando, K. Ohta, I. Iwata +3
We report results of deep optical spectroscopy with Subaru/FOCAS for Lyman Break Galaxy (LBG) candidates at z~5. So far, we made spectroscopic observations for 24 LBG candidates am…
The afterglow of GRB050709 and the nature of the short-hard gamma-ray bursts
D. B. Fox, D. A. Frail, P. A. Price +33
The final chapter in the long-standing mystery of the gamma-ray bursts (GRBs) centres on the origin of the short-hard class, suspected on theoretical grounds to result from the coa…
A log N(HI) = 22.6 DLA in a dark gamma-ray burst: the environment of GRB 050401
D. Watson, J. P. U. Fynbo, C. Ledoux +33
The optical afterglow spectrum of GRB050401 (at z=2.8992+/-0.0004) shows the presence of a DLA, with log(nHI)=22.6+/-0.3. This is the highest column density ever observed in a DLA,…
Clustering of Lyman Break Galaxies at z=4 and 5 in The Subaru Deep Field: Luminosity Dependence of The Correlation Function Slope
Nobunari Kashikawa, Makiko Yoshida, Kazuhiro Shimasaku +8
We explored the clustering properties of Lyman Break Galaxies (LBGs) at z=4 and 5 with an angular two-point correlation function on the basis of the very deep and wide Subaru Deep…
