The brightness of gamma-ray burst (GRB) afterglows and their occurrence in young, blue galaxies make them excellent probes to study star-forming regions in the distant universe. We here elucidate dust extinction properties in the early universe through the analysis of the afterglows of all known z > 6 GRBs: GRB 090423, 080913, and 050904, at z = 8.2, 6.69, and 6.295, respectively. We gather all available optical and near-infrared photometry, spectroscopy, and X-ray data to construct spectral…

X-shooting GRBs at high redshift: probing dust production history*
Evolved asymptotic giant branch (AGB) stars and Type  Ia supernovae (SNe) are important contributors to the elements that form dust in the interstellar medium of galaxies, in particular, carbon and
The Properties of GRB 120923A at a Spectroscopic Redshift of z ≈ 7.8
Gamma-ray bursts (GRBs) are powerful probes of early stars and galaxies, during and potentially even before the era of reionization. Although the number of GRBs identified at z gsim 6 remains small,
VLT/X-shooter GRBs: Individual extinction curves of star-forming regions
The extinction profiles in gamma-ray burst (GRB) afterglow spectral energy distributions (SEDs) are usually described by the small magellanic cloud (SMC)-type extinction curve. In different empirical
Constraining the nature of the most distant gamma-ray burst host galaxies
Aims. Long duration gamma-ray bursts (GRBs) allow us to explore the distant Universe, and are potentially the most effective tracer of the most distant objects. Our current knowledge of the
Star formation in the early universe: Beyond the tip of the iceberg
We present late-time Hubble Space Telescope (HST) imaging of the fields of six Swift gamma-ray bursts (GRBs) lying at 5.0 lsim z lsim 9.5. Our data include very deep observations of the field of the
Cold gas in the early Universe
We present a survey for neutral atomic-carbon (C I) along gamma-ray burst (GRB) sightlines, which probes the shielded neutral gas-phase in the interstellar medium (ISM) of GRB host galaxies at high
GRB 120521C at z ~ 6 and the Properties of High-redshift γ-Ray Bursts
We present optical, near-infrared, and radio observations of the afterglow of GRB 120521C. By modeling the multi-wavelength data set, we derive a photometric redshift of z ≈ 6.0, which we confirm
Dust reddening and extinction curves towards gamma-ray bursts at z > 4
Dust is known to be produced in the envelopes of AGB stars, the expanded shells of supernova (SN) remnants, and in situ grain growth in the ISM, although the corresponding efficiency of each of these
Exploration of the high-redshift universe enabled by THESEUS
At peak, long-duration gamma-ray bursts are the most luminous sources of electromagnetic radiation known. Since their progenitors are massive stars, they provide a tracer of star formation and

No evidence for dust extinction in GRB 050904 at z ~ 6.3
Context. Gamma-ray burst (GRB) afterglows are excellent and sensitive probes of gas and dust in star-forming galaxies at all epochs. It has been posited that dust in the early Universe must be
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 this
GRB 080913 AT REDSHIFT 6.7
We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its optical/NIR afterglow and the recognition of
Dust Extinction in High-z Galaxies with GRB Afterglow Spectroscopy - The 2175{\AA} Feature at z=2.45
We report the clear detection of the 2175A dust absorption feature in the optical afterglow spectrum of the gamma-ray burst (GRB) GRB070802 at a redshift of z=2.45. This is the highest redshift for a
Dust and metal column densities in gamma-ray burst host galaxies
In this paper we present the results from the analysis of a sample of 28 gamma-ray burst (GRB) afterglow spectral energy distributions, spanning the X-ray through to near-infrared wavelengths. This
An optical spectrum of the afterglow of a γ-ray burst at a redshift of z = 6.295
The prompt γ-ray emission from γ-ray bursts (GRBs) should be detectable out to distances of z > 10 (ref. 1), and should therefore provide an excellent probe of the evolution of cosmic star formation,
Outshining the quasars at reionization: the X-ray spectrum and light curveof the redshift 6.29 gamma-ray burst GRB 050904
Gamma-ray burst (GRB) 050904 is the most distant X-ray source known, at z = 6.295, comparable to the farthest AGNs and galaxies. Its X-ray flux decays, but not as a power law; it is dominated by

We present Keck/NIRSPEC near-IR images and Magellan/IMACS optical spectroscopy of the host galaxy of GRB 031203. The host is an actively star-forming galaxy at z ¼ 0:1055 � 0:0001. This is the lowest

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 GRB absorption
