A link between prompt optical and prompt gamma-ray emission in gamma-ray bursts.
The prompt optical emission that arrives with the gamma-rays from a cosmic gamma-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativistic ejecta of the explosion, and the ejecta's interactions with the surroundings. Until now, only GRB 990123 had been detected at optical wavelengths during the burst phase. Its prompt optical emission was variable...
متن کاملConstraining axion by polarized prompt emission from gamma ray bursts
A polarized gamma ray emission spread over a sufficiently wide energy band from a strongly magnetized astrophysical object like gamma ray bursts (GRBs) offers an opportunity to test the hypothesis of invisible axion. The axionic induced dichroism of gamma rays at different energies should cause a misalignment of the polarization plane for higher energy events relative to that one for lower ener...
متن کاملPrompt Neutrino Emission from Gamma-Ray Bursts
Recent observations show that some or possibly all long-duration gamma-ray bursts (GRBs) arise from the core collapse of massive stars. In this case, the GRB environments are believed to be preburst stellar winds. We here study prompt neutrino emission from reverse shocks as a result of the interaction of relativistic fireballs with their surrounding wind matter. We find that for reasonable par...

متن کاملPrompt Optical Observations of Gamma-Ray Bursts.
The Robotic Optical Transient Search Experiment (ROTSE) seeks to measure simultaneous and early afterglow optical emission from gamma-ray bursts (GRBs). A search for optical counterparts to six GRBs with localization errors of 1 deg2 or better produced no detections. The earliest limiting sensitivity is mROTSE>13.1 at 10.85 s (5 s exposure) after the gamma-ray rise, and the best limit is mROTSE...
