We report on Hubble Space Telescope observations of the optical transient (OT) discovered in the error box of the gamma-ray burst GRB 970508. The object was imaged on 1997 June 2 with the Space Telescope Imaging Spectrograph and Near-Infrared Camera and Multiobject Spectrometer. The observations reveal a pointlike source with R = 23.1±0.2 and H = 20.6±0.3, in agreement with the power-law temporal decay seen in ground-based monitoring. Unlike the case of GRB 970228, no nebulosity is detected… 

Evidence for a Supernova Associated with the X-Ray Flash 020903

TLDR
Ground-based and Hubble Space Telescope optical observations of the X-ray flash (XRF) 020903 show a very rapid rise in the first day, followed by a relatively slow decay in the next few days, which argues in favor of the existence of a SN associated with this XRF.

The Optical Afterglow Light Curve of GRB 980519

We present V-, R-, and I-band observations made at the US Naval Observatory, Flagstaff Station, of the afterglow of GRB 980519 on UT 1998 May 20 and 22. These observations are combined with extensive

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

The very recent detection of the faint host galaxy of one γ-ray burst and the determination of a cosmological redshift for another, demonstrates that these events are the most luminous phenomena in

Afterglows of gamma-ray bursts

Gamma-ray burst astronomy has undergone a revolution in the last three years, spurred by the discover of fading long- wavelength counterparts. We now know that at least the long duration GRBs lie at

Position and parallax of the γ-ray burst of 8 May 1997

γ-ray bursts (GRBs) have puzzled astronomers for almost three decades, primarily owing to the lack of identifications at other wavelengths. The detection of a radio counterpart enables application of

The afterglow and elliptical host galaxy of the short gamma-ray burst GRB 050724.

TLDR
The nature of the host galaxy demonstrates that short GRBs arise from an old (> 1 Gyr) stellar population, strengthening earlier suggestions and providing support for coalescing compact object binaries as the progenitors.

The afterglow and elliptical host galaxy of the short γ-ray burst GRB 050724

Despite a rich phenomenology, γ-ray bursts (GRBs) are divided into two classes based on their duration and spectral hardness—the long-soft and the short-hard bursts. The discovery of afterglow

PHENOMENOLOGY OF REVERSE-SHOCK EMISSION IN THE OPTICAL AFTERGLOWS OF GAMMA-RAY BURSTS

We use a parent sample of 118 gamma-ray burst (GRB) afterglows, with known redshift and host galaxy extinction, to separate afterglows with and without signatures of dominant reverse-shock (RS)

Reionization of the Intergalactic Medium and the Damping Wing of the Gunn-Peterson Trough

Observations of high-redshift quasars show that the intergalactic medium (IGM) must have been reionized at some redshift z > 5. If a source of radiation could be observed at the rest-frame Lyα

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 optical counterpart to the γ-ray burst GRB970508

Understanding the nature of the γ-ray burst phenomenon is one of the outstanding problems of modern astrophysics. The identification of counterparts at optical wavelengths is considered a crucial

Transient optical emission from the error box of the γ-ray burst of 28 February 1997

For almost a quarter of a century1, the origin of γ-ray bursts— brief, energetic bursts of high-energy photons—has remained unknown. The detection of a counterpart at another wavelength has long been

Spectral constraints on the redshift of the optical counterpart to the γ-ray burst of 8 May 1997

Brief, intense bursts of γ-rays occur approximately daily from random directions in space, but their origin has remained unknown since their initial detection almost 25 years ago. Arguments based on

The radio afterglow from the γ-ray burst of 8 May 1997

Important insight into the nature of γ-ray bursts (GRBs) has been gained in recent months mainly due to the immediate, precise localization of the bursts and the discovery of relatively long-lived

We present the discovery observations for the optical counterpart of the γ-ray burster GRB 970508 and discuss its light curve in the context of the fireball model. We analyze the HST data for this

Establishing the nature of γ-ray bursts is one of the greatest challenges in high-energy astrophysics. The distribution of these bursts is isotropic across the sky, but inhomogeneous in space, with a
