X-ray Polarimetry of X-ray Pulsars

Galaxies
Radiation from X-ray pulsars (XRPs) was expected to be strongly linearly polarized owing to a large difference in their ordinary and extraordinary mode opacities. The launch of IXPE allowed us to check this prediction. IXPE observed a dozen X-ray pulsars,

Studying Microquasars with X-Ray Polarimetry [PDF]

Galaxies, 2018
Microquasars are Galactic black hole systems in which matter is transferred from a donor star and accretes onto a black hole of, typically, 10–20 solar masses.

The Growth of Interest in Astronomical X-Ray Polarimetry [PDF]

Galaxies, 2018
Astronomical X-ray polarimetry was first explored in the end of the 1960s by pioneering rocket instruments. The craze arising from the first discoveries of stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters to ...

X-Ray Polarimetry as a Tool to Constrain Orbital Parameters in X-Ray Binaries

The Astrophysical Journal
X-ray binary systems consist of a companion star and a compact object in close orbit. Thanks to their copious X-ray emission, these objects have been studied in detail using X-ray spectroscopy and timing.

X-ray polarimetry on-board of HXMT [PDF]

SPIE Proceedings, 2008
The development of micropixel gas detectors, capable to image tracks produced in a gas by photoelectrons, makes possible to perform polarimetry of X-ray celestial sources in the focus of grazing incidence X-ray telescopes. HXMT is a mission by the Chinese Space Agency aimed to survey the Hard X-ray Sky with Phoswich detectors, by exploitation of the ...

XIPE: the x-ray imaging polarimetry explorer [PDF]

Space Telescopes and Instrumentation 2016: Ultraviolet to Gamma Ray, 2016
XIPE, the X-ray Imaging Polarimetry Explorer, is a mission dedicated to X-ray Astronomy. At the time of writing XIPE is in a competitive phase A as fourth medium size mission of ESA (M4). It promises to reopen the polarimetry window in high energy Astrophysics after more than 4 decades thanks to a detector that efficiently exploits the photoelectric ...

Broadband soft x-ray polarimetry [PDF]

SPIE Proceedings, 2010
We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position angle is measured to determine three Stokes parameters: I, Q, and U -- all as a ...
