The study of astronomical objects using electromagnetic radiation involves four basic observational approaches: imaging, spectroscopy, photometry (accurate counting of the photons received) and polarimetry (measurement of the polarizations of the observed photons). In contrast to observations at other wavelengths, a lack of sensitivity has prevented X-ray astronomy from making use of polarimetry. Yet such a technique could provide a direct picture of the state of matter in extreme magnetic and… 

Prospect of polarization measurements from black hole binaries in their thermal state with a scattering polarimeter

X-ray polarization measurement is a unique tool which may provide crucial information regarding the emission mechanism and the geometry of various astrophysical sources, such as neutron stars,

X-ray polarimetry with a micro pattern gas detector with pixel readout

In astronomy there are basically four kinds of observations to extract the information carried by electromagnetic radiation: photometry, imaging, spectroscopy, and polarimetry. By optimal

Hard X-ray polarimetry—an overview of the method, science drivers, and recent findings

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 measurements provide

The Instrument of the Imaging X-Ray Polarimetry Explorer

While X-ray spectroscopy, timing, and imaging have improved much since 1962 when the first astronomical nonsolar source was discovered, especially wi the launch of the Newton/X-ray Multi-Mirror

Predicting the X-ray polarization of type 2 Seyfert galaxies

Infrared, optical and ultraviolet spectropolarimetric observations have proven to be ideal tools for the study of the hidden nuclei of type-2 active galactic nuclei (AGN) and for constraining the

General History of X-Ray Polarimetry in Astrophysics

Soon after the discovery of the first extrasolar X-Ray sources it was suggested that polarimetry could play a major role as a diagnostic tool. Attempts to measure polarization of X.Ray sources was

Thermal disc emission from a rotating black hole: X-ray polarization signatures

Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be either parallel or

X-ray polarimetry is a prime tool for investigating the physics of compact objects, which has not been adequately exploited thus far. However, current low-cost technology and modest launch

Observational test for the existence of a rotating black hole in Cyg X-1

X-RAY satellite experiments1,13,14 are now investigating the degree and plane of linear polarisation of the radiation from Cyg X-1. This radiation can be explained as coming from an accretion disk

Laboratory detection of X-ray fringes with a grazing-incidence interferometer

TLDR
The prototype interferometer, having just under one millimetre of baseline, creates fringes at 1.25 keV with an angular resolution of 100 milliarcseconds, will be possible to resolve X-ray sources at 10-7 arcseconds with a larger version in orbit, three orders of magnitude better than the finest-resolution images ever achieved on the sky.

Development of a hard x-ray imaging polarimeter

An optical imaging chamber can be used to detect x-rays by imaging the tracks of photoelectrons ejected when the x-rays are absorbed in the detector volume. These tracks contain information about the
