The Imaging X-ray Polarimetry Explorer (IXPE) [PDF]

open access: yesResults in Physics, 2016
The Imaging X-ray Polarimetry Explorer (IXPE) expands observation space by simultaneously adding polarization to the array of X-ray source properties currently measured (energy, time, and location).

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

open access: yesGalaxies, 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 ...

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 ...

An Overview of X-Ray Polarimetry of Astronomical Sources

open access: yesGalaxies, 2018
We review the history of astronomical X-ray polarimetry based on the author’s perspective, beginning with early sounding-rocket experiments by Robert Novick at Columbia University and his team, of which the author was a member.

X-ray Polarimetry-Timing

open access: yes, 2023
X-ray polarimetry-timing is the characterization of rapid variability in the X-ray polarization degree and angle. As for the case of spectral-timing, it provides causal information valuable for reconstructing indirect maps of the vicinity of compact objects. To call X-ray polarimetry-timing a young field is somewhat of an understatement, given that the

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 ...

The Instrument of the Imaging X-Ray Polarimetry Explorer [PDF]

open access: yesThe Astronomical Journal, 2021
Abstract 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 Mission, Rossi/X-ray Timing Explorer, and Chandra/Advanced X-ray Astrophysics Facility, the progress of X-ray polarimetry has been ...

X-RAY AND GAMMA-RAY POLARIMETRY OF GRBS [PDF]

open access: yesEAS Publications Series, 2013
Polarimetry is expected to play a major role as a diagnostic tool for GRBs. Techniques and methods for X/Gamma ray polarimetry are reviewed including the specific problems related to the transient nature of the sources. Optical data do not encourage optimistic predictions on polarimetry of afterglows.
