We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the Lyman break falling between the I and J filters. This is by far the most distant GRB known to date. Its isotropic-equivalent energy is 3.4 × 10 53 erg in the rest-frame 110−1100 keV energy band. Despite the high redshift, both the prompt and the afterglow emission are not peculiar with respect to other GRBs. We find a… Expand
Dust Properties at z = 6.3 in the Host Galaxy of GRB 050904
We investigate the dust extinction properties in the host galaxy of GRB 050904 at z = 6.29 by analyzing simultaneous broadband observations of the optical and UV afterglow at three different epochs.Expand
GRB 050505 : a high-redshift burst discovered by Swift
We report the discovery and subsequent multiwavelength afterglow behaviour of the highredshift (z = 4.27) Gamma Ray Burst (GRB) 050505. This burst is the third most-distant burst, measured byExpand
Detection of GRB 060927 at z = 5.47: Implications for the Use of Gamma-Ray Bursts as Probes of the End of the Dark Ages*
We report on follow-up observations of the gamma-ray burst GRB 060927 using the robotic ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detectedExpand
Evidence for supernova-synthesized dust from the rising afterglow of GRB 071025 at z∼ 5
We present observations and analysis of the broad-band afterglow of Swift GRB 071025. Using optical and infrared (RIYJHK) photometry, we derive a photometric redshift of 4.4 < z < 5.2; at thisExpand
Swift observations of GRB 050904: the most distant cosmic explosion ever observed
TLDR
The light curve observed by the XRT is characterized by the presence of a long flaring activity lasting up to 1-2 h after the burst onset in the burst rest frame, with no evidence of a smooth power-law decay following the prompt emission as seen in other GRBs. Expand
The weak INTEGRAL bursts GRB 040223 and GRB 040624: an emerging population of dark afterglows
We report here γ -ray, X-ray and near-infrared observations of GRB 040223 along with γ -ray and optical observations of GRB 040624. GRB 040223 was detected by INTEGRAL close to the Galactic plane andExpand
The high-redshift gamma-ray burst GRB 140515A - A comprehensive X-ray and optical study
High-redshift gamma-ray bursts (GRBs) offer several advantages when studying the distant Universe, providing unique information about the structure and properties of the galaxies in which theyExpand
Probing the neutral fraction of the IGM with GRBs during the epoch of reionization
We show that near-infrared observations of the red side of the Lya line from a single gamma-ray burst (GRB) afterglow cannot be used to constrain the global neutral fraction of the intergalacticExpand
The Hubble Diagram to Redshift >6 from 69 Gamma-Ray Bursts
One of the few ways to measure the properties of dark energy is to extend the Hubble diagram (HD) to higher redshifts with gamma-ray bursts (GRBs). GRBs have at least five properties (their spectralExpand
A Mean Redshift of 2.8 for Swift gamma - ray bursts
TLDR
The high mean redshift of GRBs and their wide redshift range clearly demonstrates their suitability as efficient probes of galaxies and the intergalactic medium over a significant fraction of the history of the Universe. Expand
