We present K-band imaging observations of ten gamma-ray burst (GRB) host galaxies for which an optical and/or radio afterglow associated with the GRB event was clearly identified. Data were obtained with the Very Large Telescope and New Technology Telescope at ESO (Chile), and with the Gemini-North telescope at Mauna Kea (Hawaii). Adding to our sample nine other GRB hosts with K-band photometry and determined redshifts published in the literature, we compare their observed and absolute K…

Abstract Gamma-ray bursts (GRBs) are cosmologically distributed, very energetic and very transient sources detected in the γ-ray domain. The identification of their x-ray and optical afterglows

New light on gamma-ray burst host galaxies with Herschel

Until recently, dust emission has been detected in very few host galaxies of gamma-ray bursts (GRBHs). With Herschel, we have now observed 17 GRBHs up to redshift z ~ 3 and detected 7 of them at


We present a study of 15 long-duration γ-ray burst (GRB) host galaxies at z > 2. The GRBs are selected with available early-time afterglow spectra in order to compare interstellar medium (ISM)

A Search for Host Galaxies of 24 Gamma-Ray Bursts

We report the results from observations of 24 gamma-ray burst (GRB) fields from 2005 and 2006 undertaken at the Danish 1.54 m telescope at ESO/La Silla. Photometry and positions for two previously

Infrared and Optical Observations of GRB 030115 and its Extremely Red Host Galaxy: Implications for Dark Bursts*

We present near-infrared (NIR) and optical observations of the afterglow of GRB 030115. Discovered in an infrared search at Kitt Peak 5 hr after the burst trigger, this afterglow is the faintest ever


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

A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225

Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at

The submillimetre properties of gamma-ray burst host galaxies

Long-duration gamma-ray bursts (GRBs) accompany the deaths of some massive stars and hence, because massive stars are short-lived, are a tracer of star formation activity. Given that GRBs are bright

UV star-formation rates of GRB host galaxies

We study a magnitude-limited sample of 10 gamma-ray burst (GRB) host galaxies with known spectroscopic red- shifts (0.43 < z < 2.04). From an analysis of the spectral energy distributions (SEDs),

Spitzer Observations of Gamma-Ray Burst Host Galaxies: A Unique Window into High-Redshift Chemical Evolution and Star Formation

We present deep 3.6 μm observations of three z ~ 5 GRB host galaxies with the Spitzer Space Telescope. The host of GRB 060510B, at z = 4.942, is detected with a flux density of 0.23 ± 0.04 μJy,



Are Starburst Galaxies the Hosts of Gamma-Ray Bursts?

We present deep 2.2 μm imaging of 12 gamma-ray burst host galaxies. Template spectral energy distributions are fitted to the multiband photometry between visible and near-infrared wavelengths to

SCUBA observations of the host galaxies of four dark gamma-ray bursts

It is indicated that optically dark GRBs are not especially associated with very submillimetre-luminous galaxies and so cannot be used as reliable indicators of dust-enshrouded massive star formation activity.

The Host Galaxy of the Gamma-Ray Burst 971214

We report on Hubble Space Telescope (HST) observations of the host galaxy of GRB 971214, taken 4 months after the burst. The redshift of the proposed host galaxy at z=3.418, combined with optical and

The Bright Gamma-Ray Burst of 2000 February 10: A Case Study of an Optically Dark Gamma-Ray Burst

The gamma-ray burst GRB 000210 had the highest gamma-ray peak flux of any event localized by BeppoSAX as yet, but it did not have a detected optical afterglow, despite prompt and deep searches down

The Observed Offset Distribution of Gamma-Ray Bursts from Their Host Galaxies: A Robust Clue to the Nature of the Progenitors

We present a comprehensive study to measure the locations of gamma-ray bursts (GRBs) relative to their host galaxies. In total, we find the offsets of 20 long-duration GRBs from their apparent host

Very Large Telescope and Hubble Space Telescope Observations of the Host Galaxy of GRB 990705

We present Very Large Telescope spectroscopic observations of the GRB 990705 host galaxy and highlight the benefits provided by the prompt phase features of gamma-ray bursts (GRBs) to derive the

Identification of a host galaxy at redshift z = 3.42 for the γ-ray burst of 14 December 1997

Knowledge of the properties of γ-ray bursts has increased substantially following recent detections of counterparts at X-ray, optical and radio wavelengths. But the nature of the underlying physical

The Host Galaxy of GRB 970508

We present late-time imaging and spectroscopic observations of the optical transient (OT) and host galaxy of GRB 970508. Imaging observations roughly 200 and 300 days after the burst provide

Gamma-Ray Burst Host Galaxies Have “Normal” Luminosities

All current evidence points to gamma-ray burst host galaxies being normal in luminosity, with a new solution to the dilemma of bright bursts at distances for which host galaxies with a normal luminosity will not violate the observed limits.

Gamma-ray bursts and the history of star formation

Popular models for the origin of gamma-ray bursts (GRBs) include short-lived massive stars as the progenitors of the fireballs. Hence the redshift distribution of GRBs should track the cosmic star
