Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

The cosmological gamma-ray burst (GRB) phenomenon is reviewed. The broad
observational facts and empirical phenomenological relations of the GRB prompt emission …

Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and
mechanism are the focus of intense research and debate. More than three decades after …

The formation and large-scale propagation of Poynting-dominated jets produced by
accreting, rapidly rotating black hole systems are studied by numerically integrating the …

We report the polarization measurement in prompt γ-ray emission of GRB 100826A with the
Gamma-Ray Burst Polarimeter on board the small solar-power-sail demonstrator IKAROS …

Rotating black holes probably power ultrarelativistic jets in gamma-ray bursts, relativistic jets
from some active galactic nuclei, and jets from some black hole X-ray binaries. Prior …

Gamma-ray bursts (GRBs) are the strongest explosions in the Universe since the Big Bang.
They are believed to be produced either in the formation of black holes at the end of massive …

The emission mechanism and the origin and structure of magnetic fields in gamma-ray burst
(GRB) jets are among the most important open questions concerning the nature of the …

Polarization measurements provide a direct insight into the nature of astrophysical
processes. Unfortunately, only a few instruments are available for this kind of measurement …

A previous analysis of the Reuven Ramaty High Energy Solar Spectroscopic Imager
(RHESSI) observation of GRB 021206 found that the γ-ray flux was 80±20 per cent …
