IXPE Observations of the Quintessential Wind-accreting X-Ray Pulsar Vela X-1
The Astrophysical Journal Letters, 2023 The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-resolved polarimetry of X-ray pulsars is required in order to test different ...

, 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

The Growth of Interest in Astronomical X-Ray Polarimetry
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 ...

An X-ray polarimeter for hard X-ray optics [PDF]
, 2006 Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

Searching for Axion-Like Particles with X-ray Polarimeters
Galaxies, 2018 X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction between photons and axion-like particles (ALPs).

Galactic X-ray Polarimetry and High-Resolution X-ray Spectroscopy [PDF]
Symposium - International Astronomical Union, 1973 Stellar X-ray spectroscopy and polarimetry are discussed in terms of the source parameters that can be determined through such studies and in terms of the constraints that these studies will place on theoretical models. The spectroscopic and polarimetric results that have been obtained to date are reviewed.

The Imaging X-ray Polarimetry Explorer
, 2021 The Imaging X-ray Polarimetry Explorer is the next NASA Small Explorer developed in collaboration with the Italian Space Agency (Agenzia Spaziale Italiana, ASI). The mission, selected in 2017, is dedicated to imaging polarimetry in the 2-8 keV energy range and the payload comprises of three identical telescopes, each composed of a grazing-incidence ...
