Over half a century from the discovery of gamma-ray bursts (GRBs), the dominant radiation
mechanism responsible for their bright and highly variable prompt emission remains poorly …

Context. Despite over 50 years of research, many open questions remain about the origin
and nature of gamma-ray bursts (GRBs). Linear polarization measurements of the prompt …

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 POLAR detector is a space based Gamma Ray Burst (GRB) polarimeter with a wide
field of view, which covers almost half the sky. The instrument uses Compton scattering of …

The prompt emission of GRBs has been investigated for more than 50 years but remains
poorly understood. Commonly, spectral and temporal profiles of γ-ray emission are …

Context. Simultaneous γ-ray measurements of γ-ray burst spectra and polarization offer a
unique way to determine the underlying emission mechanism (s) in these objects, as well as …

The X/gamma-ray polarimetry of the Crab pulsar/nebula is believed to hold crucial
information on their emission models. In the past, several missions have shown evidence of …

Photons preferentially Compton scatter perpendicular to the plane of polarization. This
property can be exploited to design instruments to measure the linear polarization of hard X …

摘要天文学是一门观测学科, 其发展受观测技术及仪器进步所推动, 而天文科学发展同样不断对
观测仪器提出新的要求. 天文学发展至今, 对观测仪器的要求逐渐走向极致和极端 …

As the most powerful events since the Big Bang, Gamma-Ray Bursts (GRBs) typically emit in
a few seconds the amount of energy that the Sun would deliver in its entire life. These …
