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 thought to be a key to understanding the nature of these bursts (see, for example, ref. 2), but intensive searches have not revealed such a counterpart. The distribution and properties of the bursts3 are explained naturally if they lie at cosmological distances (a few Gpc)4, but there is a… 
The decay of optical emission from the γ-ray burst GRB970228
Re-evaluate the existing photometry of the optical counterpart of the γ-ray burst GRB970228 to construct an optical light curve for the transient event and finds that between 21 hours and six days after the burst, the R-band brightness decreased by a factor of ∼40.
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
An unusual supernova in the error box of the γ-ray burst of 25 April 1998
The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio wavelengths and the measurement of the redshifts of some of these events, has established that γ-ray bursts lie at
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 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
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
Discovery of an X-ray afterglow associated with the γ-ray burst of 28 February 1997
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
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
Evidence for Diverse Optical Emission from Gamma-Ray Burst Sources
Optical Transients from gamma-ray burst sources, in addition to offering a distance determination, convey important information about the physics of the emission mechanism, and perhaps also about the


Gamma-ray bursters at cosmological distances
It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy
Spatial distribution of γ-ray bursts observed by BATSE
THE nature of the sources of cosmic γ-ray bursts is a long-standing problem in astrophysics. Lack of knowledge of their true spatial distribution and of their intrinsic brightness has hampered
Rapid searches for counterparts of GRB 930131
A fading counterpart to a gamma-ray burst (GRB) would appear as a point source inside a GRB error region soon after the burst which dims on a timescale from minutes to days. The favorable
Gamma-ray bursts and the structure of the Galactic halo
We have systematically investigated Galactic models for classical gammaray bursts (GRBs) in which gamma-ray bursters are ejected from the Galactic disk. It is relatively easy to construct models in
Flickering Faint Galaxies: Few and Far Between
Optical variability in galaxies at high redshift is a tracer of evolution in AGN activity, and should provide a useful constraint on models of galaxy evolution, AGN structure, and cosmology. We

The GROCSE I experiment (Gamma-Ray Optical Counterpart Search Experiment) is a rapid slewing wide field of view optical telescope at Lawrence Livermore National Laboratory which responds to triggers
Observations of Gamma-Ray Bursts of Cosmic Origin
Sixteen short bursts of photons in the energy range 0.2–1.5 MeV have been observed between 1969 July and 1972 July using widely separated spacecraft. Burst durations ranged from less than 0.1 s to
ROSAT Detection and High Precision Localization of X-ray Sources in the November 19, 1978 Gamma-Ray Burst Error Box
We report on observations of the 1978 November 19 gamma-ray burst source, performed with the ROSAT X-ray HRI experiment. Two sources were detected, one of which is possibly variable. The latter
SAX: the wideband mission for x-ray astronomy
ABSTRACT In the framework of past and future X-ray missions the SAX satellite, to be launched in March 1996, stands out for its very wide spectral coverage from 0. 1 to 200 keV, with well balanced
