Pulsar systems accelerate particles to immense energies. The detailed functioning of these engines is still poorly understood, but polarization measurements of high-energy radiation may allow us to locate where the particles are accelerated. We have detected polarized gamma rays from the vicinity of the Crab pulsar using data from the spectrometer on the International Gamma-Ray Astrophysics Laboratory satellite. Our results show polarization with an electric vector aligned with the spin axis of… Expand
Gamma-Ray Polarimetry
Gamma-ray polarimetry can provide a powerful diagnostic of the high-energy physics at work in the most extreme sources of the universe: active galactic nuclei, gamma-ray bursts, black hole binaries,Expand
High-energy astrophysics — energies above 100 keV
Gamma-rays represent the most energetic photons of the electromagnetic spectrum. Astronomy with gamma-rays, therefore, allows the study of the most compact, energetic and violent objects in theExpand
Phase-resolved X-ray polarimetry of the Crab pulsar with the AstroSat CZT Imager
The Crab pulsar is a typical example of a young, rapidly spinning, strongly magnetized neutron star that generates broadband electromagnetic radiation by accelerating charged particles to near lightExpand
Polarization of the Crab Pulsar and Nebula as Observed by the INTEGRAL/IBIS Telescope
Neutron stars generate powerful winds of relativistic particles that form bright synchrotron nebulae around them. Polarimetry provides a unique insight into the geometry and magnetic configuration ofExpand
Polarized synchrotron emission from the equatorial current sheet in gamma-ray pulsars
Polarization is a powerful diagnostic tool to constrain the site of the high-energy pulsed emission and particle acceleration in gamma-ray pulsars. Recent particle-in-cell simulations of pulsarExpand

Gamma-Ray Flares from the Crab Nebula
Two separate gamma-ray flares from a young and energetic pulsar powers the well-known Crab Nebula are described and it is suggested that the gamma rays were emitted via synchrotron radiation from peta–electron-volt electrons in a region smaller than 1.4 × 10−2 parsecs. Expand
Polarization of neutron star surface emission: a systematic analysis
New-generation X-ray polarimeters currently under development promise to open a new window in the study of high-energy astrophysical sources. Among them, neutron stars appear particularly suited forExpand
Multiwavelength Polarization of Rotation-Powered Pulsars
Polarization measurements provide strong constraints on models for emission from rotation-powered pulsars. We present multiwavelength polarization predictions showing that measurements over a rangeExpand
High Energy Polarization of Blazars : Detection Prospects
Emission from blazar jets in the ultraviolet, optical, and infrared is polarized. If these low-energy photons were inverse-Compton scattered, the upscattered high-energy photons retain a fraction ofExpand
