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 underlying energy source. As the gamma-ray phenomenon is extremely diverse, with timescales spanning several orders of magnitude, some diversity in optical counterpart signatures appears plausible. We have studied the optical transient that accompanied the gamma-ray burst of 1997 May 8, GRB 970508…

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

Gamma‐ray burst optical follow ups with robotic telescopes

Gamma-ray bursts (GRBs) are the most energetic phenomenon in the universe, emitting their energy throughout the electromagnetic spectrum. Due to their initial brightness and highly transient nature,

Cosmic Gamma-Ray Bursts

Since their discovery in 1973, Gamma-Ray Bursts (GRBs) have remained for many years one of the most elusive mysteries in High Energy-Astrophysics. Despite the fact that ∼800 GRBs are detected every

Broadband observations of the naked-eye γ-ray burst GRB 080319B

Observations of the extraordinarily bright prompt optical and γ-ray emission of GRB 080319B that provide diagnostics within seconds of its formation, followed by broadband observations of the afterglow decay that continued for weeks.

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

Identification of Two Categories of Optically Bright Gamma-Ray Bursts

We present the results of a systematic analysis of the intrinsic optical afterglow light curves for a complete sample of gamma-ray bursts (GRBs) observed in the period from 1997 February to 2005

Snapshot Identification of Gamma-Ray Burst Optical Afterglows

Gamma-ray burst afterglows can be identified in single-epoch observations using three or more optical filters. This method relies on color measurements to distinguish the power-law spectrum of an

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

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

The discovery of fading but relatively long-lived X-ray emission accompanying γ-ray bursts has revolutionized the study of these objects. This ‘afterglow’ is most easily explained by models similar



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

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 Soft X-Ray Afterglow of Gamma-Ray Bursts, A Stringent Test for the Fireball Model

I consider the recent discovery of a soft X-ray source inside the error box of the gamma-ray burst GB 960720 by the SAX, ASCA, and ROSAT satellites, in terms of the fireball model. I show that the

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

SN 1987A Light Curves

The observation of the light curves of SN1987A over a wide range of wavelengths is perhaps the most straightforward way of studying the energy generation and dissipation within the supernova. The


A study is made of stellar and galaxy colors using a spectrophotometric synethesis technique. We show that use of good color response functions and a modern determination of the spectroscopic energy

Optical counterparts of cosmological GRBs

The possibility of observing of optical counterparts of cosmological GRBs has been considered assuming that the counterparts are due to the γ-radiation interaction with the interstellar medium.

Observations of GRB 970228 and GRB 970508 and the Neutron Star Merger Model

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
