Neutron star mergers are the canonical multimessenger events: they have been observed
through photons for half a century, gravitational waves since 2017, and are likely to be …

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 …

We present the IXPE observation of GRB 221009A, which includes upper limits on the linear
polarization degree of both prompt and afterglow emission in the soft X-ray energy band …

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 …

Abstract The Cadmium Zinc Telluride Imager (CZTI) on board AstroSat has been regularly
detecting gamma-ray bursts (GRBs) since its launch in 2015. Its sensitivity to polarization …

The Crab pulsar is a typical example of a young, rapidly spinning, strongly magnetized
neutron star that generates broadband electromagnetic radiation by accelerating charged …

The radiation mechanism underlying the prompt emission remains unresolved and can be
resolved using a systematic and uniform time-resolved spectro-polarimetric study. In this …

The last decade has seen a leapfrog in the interest of X-ray polarimetry with a number of
new polarization measurements in hard X-rays from AstroSat, POLAR, GAP, and PoGO+ …

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 …

Lorentz invariance is one of the fundamental tenets of Special Relativity, and has been
extensively tested with laboratory and astrophysical observations. However, many quantum …
