We report on observations of the field of GRB 970508 made in 1998 early August, 454 days after outburst, with the STIS CCD camera on board the Hubble Space Telescope (HST). The images, taken in open filter (50CCD) mode, clearly reveal the presence of a galaxy that was overwhelmed in earlier (1997 June) HST images by emission from the optical transient (OT). The galaxy is regular in shape: after correcting for the HST/STIS PSF, it is well fitted by an exponential disk with a scale length of 0… 

Hubble Space Telescope and Ground-based Optical and Ultraviolet Observations of GRB 010222

We report on Hubble Space Telescope (HST) Wide Field Planetary Camera 2 optical and Space Telescope Imaging Spectrograph (STIS) near-ultraviolet MAMA observations and ground-based optical

The host galaxy of GRB 990712

We present a comprehensive study of the z = 0.43 host galaxy of GRB 990712, involving ground-based photometry, spectroscopy, and HST imaging. The broad-band UBVRIJHKs photometry is used to determine

The line-of-sight towards GRB 030429 at z =2.66: Probing the matter at stellar, galactic and intergalactic scales

We report the discovery of the optical afterglow (OA) of the long-duration gamma-ray burst GRB 030429, and present a comprehensive optical/near-infrared dataset used to probe the matter at different

Are the hosts of gamma-ray bursts sub-luminous and blue galaxies?

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

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

Gamma-Ray Burst-Selected High-Redshift Galaxies: Comparison to Field Galaxy Populations to z ~ 3

We study the internal structural properties of 37 long-duration gamma-ray burst (GRB) host galaxies imaged with the Hubble Space Telescope (HST). Our goal is to gain insights in the types of galaxies

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

Probing Cosmic Star Formation Using Long Gamma-Ray Bursts: New Constraints from the Spitzer Space Telescope*

We report on IRAC 4.5 μm, IRAC 8.0 μm, and MIPS 24 μm deep observations of 16 gamma-ray burst (GRB) host galaxies performed with the Spitzer Space Telescope, and we investigate in the thermal

Gamma-Ray Bursts: The Afterglow Revolution

GRBs were discovered with the Vela satellites, whose main purpose was to verify compliance with the 1963 Limited Nuclear Test Ban Treaty. Since their discovery these events, which emit the bulk of

Numerical counterparts of GRB host galaxies

We explore galaxy properties in general and properties of host galaxies of gammaray bursts (GRBs) in particular, using N-body/Eulerian hydrodynamic simulations and the stellar population synthesis



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

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 optical counterpart to γ-ray burst GRB970228 observed using the Hubble Space Telescope

Although more than 2,000 astronomical γ-ray bursts (GRBs) have been detected, and numerous models proposed to explain their occurrence1, they have remained enigmatic owing to the lack of an obvious

The Hubble Deep Field (HDF) is a Director’s Discretionary program on HST in Cycle 5 to image an undistinguished field at high Galactic latitude in four passbands as deeply as reasonably possible.

Optical afterglow of the γ-ray burst of 14 December 1997
