X-ray polarimetry: historical remarks and other considerations [PDF]

open access: yes, 2010
We briefly discuss the history of X-ray polarimetry for astronomical applications including a guide to the appropriate statistics. We also provide an introduction to some of the new techniques discussed in more detail elsewhere in these proceedings. We conclude our discussion with our concerns over adequate ground calibration, especially with respect ...

Imaging X-ray Polarimetry Explorer: prelaunch

open access: yesJournal of Astronomical Telescopes, Instruments, and Systems, 2022
Launched on 2021 December 9, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission will open a new window of investigation—imaging x-ray polarimetry. The observatory features three identical telescopes, each consisting of a mirror module assembly with a ...

X-ray polarimetry of X-ray pulsar X Persei: another orthogonal rotator?

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT X Persei is a persistent low-luminosity X-ray pulsar of period of ≈ 835 s in a Be binary system. The field strength at the neutron star surface is not known precisely, but indirect signs indicate a magnetic field above 1013 G, which makes the object one of the most magnetized known X-ray pulsars.

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

open access: yesSpace 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 ...

Probing Magnetic Fields and Acceleration Mechanisms in Blazar Jets with X-ray Polarimetry

open access: yesGalaxies, 2021
X-ray polarimetry promises us an unprecedented look at the structure of magnetic fields and on the processes at the base of acceleration of particles up to ultrarelativistic energies in relativistic jets.

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

open access: yesSPIE 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 ...

Photoelectric Polarimetry and the Gas Pixel Detector Yesterday, Today and Tomorrow

open access: yesGalaxies, 2018
Since the very beginning of X-ray Astronomy, polarimetry has been suggested as a tool of diagnostics, of great potentiality. While almost all measurements of X-rays were based on detectors using the photoelectric effect, the first attempt to perform ...
