Long-duration γ-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation from the collapse of massive stars. Previous early optical observations of even the most exceptional GRBs (990123 and 030329) lacked both the temporal resolution to probe the optical flash in detail and the accuracy needed to trace the transition from the prompt emission within the outflow to external shocks caused by… 
Prompt Emission of GRB 121217A from Gamma-Rays to the Near-Infrared
The mechanism that causes the prompt-emission episode of gamma-ray bursts (GRBs) is still widely debated despite there being thousands of prompt detections. The favoured internal shock model relates
Prompt optical emission and synchrotron self-absorption constraints on emission site of GRBs
We constrain the distance of the gamma-ray burst (GRB) prompt emission site from the explosion centre R, by determining the location of the electron's self-absorption frequency in the GRB prompt

Some of the milestones made in GRB research during the Swift era are summarized, and how previous widely accepted theoretical models have had to adapt to accommodate the new wealth of observational data are summarized.
Prompt high-energy emission from gamma-ray bursts in the internal shock model
Context. Gamma-ray bursts (GRB) are powerful, short duration events with a spectral luminosity peaking in the keV-MeV (BATSE) range. The prompt emission is thought to arise from electrons accelerated
GRB 080319B: evidence for relativistic turbulence, not internal shocks
We show that the excellent optical and gamma-ray data available for GRB 080319B rule out the internal shock model for the prompt emission. The data instead point to a model in which the observed
Gamma-Ray Burst Jets and their Radio Observations
Abstract Radio observations play a key role in studying the jets that power GRBs, the most luminous cosmic explosions. They are crucial for determining the GRB jet energy, the external density, and
Photospheric Prompt Emission From Long Gamma-ray Burst Simulations. I. Optical Emission
A complete understanding of gamma-ray bursts (GRBs) has been difficult to achieve, due to our incomplete knowledge of the radiation mechanism that is responsible for producing the prompt emission.
Gamma Ray Bursts -- A radio perspective
Gamma-ray bursts (GRBs) are extremely energetic events at cosmological distances. They provide unique laboratory to investigate fundamental physical processes under extreme conditions. Due to extreme


The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across the electromagnetic
An infrared flash contemporaneous with the γ-rays of GRB 041219a
The explosion that results in a cosmic γ-ray burst (GRB) is thought to produce emission from two physical processes: the central engine gives rise to the high-energy emission of the burst through
A link between prompt optical and prompt γ-ray emission in γ-ray bursts
The prompt optical emission that arrives with the γ-rays from a cosmic γ-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativistic ejecta of the
Observation of contemporaneous optical radiation from a γ-ray burst
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
A common origin for cosmic explosions inferred from calorimetry of GRB030329
Radio observations of GRB030329 indicate a common origin for cosmic explosions in which the energy in the highest-velocity ejecta is extremely variable, and the contribution of the γ-rays is energetically minor.
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
What did we learn from gamma-ray burst 080319B?
The optical and gamma-ray observations of GRB 080319B allow us to provide a broad-brush picture for this remarkable burst. The data indicate that the prompt optical and gamma-ray photons were
We present a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances, and we derive their conical opening angles based on observed broadband breaks in their light curves.
Afterglow Emission from Naked Gamma-Ray Bursts
We calculate the afterglow emission for gamma-ray bursts (GRBs) going off in an extremely low density medium, referred to as naked bursts. Our results also apply to the case where the external medium
Energetics and Luminosity Function of Gamma-Ray Bursts
Gamma-ray bursts (GRBs) are believed to be some catastrophic event in which material is ejected at a relativistic velocity, and internal collisions within this ejecta produce the observed γ-ray
