# Galaxies: High-Redshift

## The case for a high-redshift origin of GRB 100205A

The number of long gamma-ray bursts (GRBs) known to have occurred in the distant Universe (z > 5) is small (̃15); however, these events provide a powerful way of probing star formation at the onset of galaxy evolution. In this paper, we present …

## Photometry and spectroscopy of GRB 060526: a detailed study of the afterglow and host galaxy of a z = 3.2 gamma-ray burst

Aims: With this paper we want to investigate the highly variable afterglow light curve and environment of gamma-ray burst (GRB) 060526 at z = 3.221. Methods: We present one of the largest photometric datasets ever obtained for a GRB afterglow, …

## Erratum: Low-Resolution Spectroscopy of Gamma-Ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers'' <A href=/abs/2009ApJS..185..526F''>(2009, ApJS, 185, 526)</A>

In this paper, Figure 14 is incomplete due to an error during production. We here provide the missing sub-figures. Based on observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere, Chile, under …

## Low-resolution Spectroscopy of Gamma-ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers

We present a sample of 77 optical afterglows (OAs) of Swift detected gamma-ray bursts (GRBs) for which spectroscopic follow-up observations have been secured. Our first objective is to measure the redshifts of the bursts. For the majority (90%) of …

## The Host Galaxies of Swift Dark Gamma-ray Bursts: Observational Constraints on Highly Obscured and Very High Redshift GRBs

In this work, we present the first results of our imaging campaign at Keck Observatory to identify the host galaxies of dark'' gamma-ray bursts (GRBs), events with no detected optical afterglow or with detected optical flux significantly fainter …

## Observations of the Naked-Eye GRB 080319B: Implications of Nature's Brightest Explosion

The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across the electromagnetic spectrum. We present our detailed optical and …

## Discovery of a Transient U-Band Dropout in a Lyman Break Survey: A Tidally Disrupted Star at z=3.3?

We report the discovery of a transient source in the central regions of galaxy cluster A267. The object, which we call PALS-1, was found in a survey aimed at identifying highly magnified Lyman break galaxies in the fields of intervening rich …

## Keck Spectroscopy and Hubble Space Telescope Imaging of GRB 000926: Probing a Host Galaxy at z = 2.038

We present early-time Keck spectroscopic observations and late-time Hubble Space Telescope (HST) imaging of GRB 000926. The HST images show a small offset between the optical transient and a bright, compact knot in the host galaxy. Combined with the …

## The Broadband Afterglow of GRB 980329

We present radio observations of the afterglow of the bright γ-ray burst GRB 980329 made between 1 month and several years after the burst, a reanalysis of previously published submillimeter data, and late-time optical and near- infrared (NIR) …

## The Unusually Long Duration Gamma-Ray Burst GRB 000911: Discovery of the Afterglow and Host Galaxy

Of all the well-localized gamma-ray bursts, GRB 000911 has the longest duration (T$_90$=500 s) and ranks in the top 1% of BATSE bursts for fluence. Here we report the discovery of the afterglow of this unique burst. In order to simultaneously fit our …
