The origin of γ-ray bursts (GRBs) has been enigmatic since their discovery. The situation improved dramatically in 1997, when the rapid availability of precise coordinates, for the bursts allowed the detection of faint optical and radio afterglows — optical spectra thus obtained have demonstrated conclusively that the bursts occur at cosmological distances. But, despite efforts by several groups, optical detection has not hitherto been achieved during the brief duration of a burst. Here we… 

Prompt Optical Emission from Gamma-ray Bursts

The Robotic Optical Transient Search Experiment (ROTSE) seeks to measure contemporaneous and early afterglow optical emission from gamma-ray bursts (GRBs). The ROTSE-I telescope array has been fully

Early optical emission from the γ-ray burst of 4 October 2002

Observations of the long-lived emission—or ‘afterglow’—of long-duration γ-ray bursts place them at cosmological distances, but the origin of these energetic explosions remains a mystery. Observations

Discovery of Early Optical Emission from GRB 021211

We report our discovery and early-time optical, near-infrared, and radio wavelength follow-up observations of the afterglow of the gamma-ray burst GRB 021211. Our optical observations, beginning 21

Gamma-ray Bursts

Since their discovery in 1967, Gamma-ray bursts (GRBs) have been puzzling to astrophysicists. With the advent of a new generation of X-ray satellites in the late 90’s, it was possible to carry out

Multiwavelength Observations of GRB 050820A: An Exceptionally Energetic Event Followed from Start to Finish

We present observations of the unusually bright and long γ-ray burst GRB 050820A, one of the best sampled broadband data sets in the Swift era. The γ-ray light curve is marked by a soft precursor

Very Early Optical Afterglows of Gamma-Ray Bursts: Evidence for Relative Paucity of Detection

Comparisons of the X-ray afterglow flux to the optical after glow flux and prompt γ-ray fluence is used to quantify the seemingly deficient optical, and in some cases X-rays, light at these early epochs.

A Search for Early Optical Emission from Short- and Long-Duration Gamma-Ray Bursts

Gamma-ray bursts of short duration may harbor vital clues to the range of phenomena producing bursts. However, recent progress from the observation of optical counterparts has not benefited the study

Prompt Optical Observations of GRB 050319 with the Swift UVOT

The UVOT telescope on the Swift observatory has detected optical afterglow emission from GRB 050319. The flux declined with a power-law slope of α = -0.57 between the start of observations some 230 s

GRB 061121: Broadband Spectral Evolution through the Prompt and Afterglow Phases of a Bright Burst

Swift triggered on a precursor to the main burst of GRB 061121 (z = 1.314), allowing observations to be made from the optical to gamma-ray bands. Many other telescopes, including Konus-Wind,


A multi-wavelength study of GRB 081008 by Swift, ROTSE-III, and Gamma-Ray Burst Optical/NearInfrared Detector suggests the early optical variability may be from continuous energy injection into the forward shock front by later shells producing the second epoch of burst activities.



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

The first X – ray localization of a γ – ray burst by BeppoSAX and its fast spectral evolution

In this paper we present the observations performed by the BeppoSAX Gamma–Ray Burst Monitor (GRBM) and Wide Field Cameras (WFC) of GB960720. We derive a precise localization (3 arcmin radius) and

GRB 990123: Evidence that the Gamma Rays Come from a Central Engine

GRB 990123 was a long, complex gamma-ray burst with an optical transient that started early within the gamma-ray phase. The peak and power-law decay of the early optical emission strongly indicate

New Constraints on Simultaneous Optical Emission From Gamma-Ray Bursts Measured by the Livermore Optical Transient Imaging System Experiment

LOTIS is a gamma-ray burst optical counterpart search experiment located near Lawrence Livermore National Laboratory in California. Since operations began in 1996 October, LOTIS has responded to five

Searches for optical counterparts of BATSE gamma-ray bursts with the Explosive Transient Camera

The Explosive Transient Camera (ETC) is a wide-field CCD camera system capable of detecting short (1–10 s) celestial optical flashes as faint as m∼10 over a field-of-view of 0.75 steradians between

Results from Gamma-Ray Optical Counterpart Search Experiment: A Real Time Search for Gamma-Ray Burst Optical Counterparts

The Gamma-Ray Optical Counterpart Search Experiment (GROCSE) has searched for contemporaneous optical counterparts to gamma-ray bursts (GRBs) using an automated rapidly slewing wide field of view

Optical and Long-Wavelength Afterglow from Gamma-Ray Bursts

We discuss the evolution of cosmological gamma-ray burst remnants, consisting of the cooling and expanding fireball ejecta together with any swept-up external matter, after the gamma-ray event. We


We calculate the expected spectrum and light curves of the early afterglow. For short GRBs the peak of the afterglow will be delayed, typically, by few dozens of seconds after the burst. The X-ray

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
