The association of GRB 060218 with a supernova and the evolution of the shock wave
Although the link between long γ-ray bursts (GRBs) and supernovae has been established, hitherto there have been no observations of the beginning of a supernova explosion and its intimate link to aExpand

An extremely luminous X-ray outburst at the birth of a supernova
Massive stars end their short lives in spectacular explosions—supernovae—that synthesize new elements and drive galaxy evolution. Historically, supernovae were discovered mainly through theirExpand

Observations suggest that {gamma}-ray bursts (GRBs) are produced by the dissipation of the kinetic energy of a relativistic fireball. We show that a large fraction, {ge}10{percent}, of the fireballExpand

Magnetic Fields in Starburst Galaxies and the Origin of the FIR-Radio Correlation
We estimate minimum energy magnetic fields (Bmin) for a sample of galaxies with measured gas surface densities, spanning more than four orders of magnitude in surface density, from normal spirals toExpand

The Luminosity and Angular Distributions of Long‐Duration Gamma‐Ray Bursts
The realization that the total energy of gamma-ray bursts (GRBs) is correlated with their jet break angles motivates the search for a similar relation between the peak luminosity L and the jet breakExpand

We derive a simple approximate model describing the early, hours to days, UV/optical (UV/O) supernova emission, which is produced by the expansion of the outer 10–2 M ☉ part of the shock-heatedExpand

Dust Sublimation by Gamma-ray Bursts and Its Implications
The prompt optical flash recently detected accompanying GRB 990123 suggests that, for at least some γ-ray bursts (GRBs), γ-ray emission is accompanied by prompt optical-UV emission with luminosityExpand

γ-Ray Burst Afterglow: Confirming the Cosmological Fireball Model
The recent detection of delayed X-ray and optical emission—"afterglow"—associated with γ-ray bursts (GRBs) supports models in which the bursts are produced by relativistic expanding blastExpand

A 450 Day Light Curve of the Radio Afterglow of GRB 970508: Fireball Calorimetry
We report on the results of an extensive monitoring campaign of the radio afterglow of GRB 970508, lasting 450 days after the burst. The spectral and temporal radio behavior indicate that theExpand
