The First X-ray Polarization Observation of the Black Hole X-ray Binary 4U 1630-47 in the Steep Power Law State

Nicole Rodriguez Cavero, +107 more
TL;DR: In this paper , the power-law component of the black hole X-ray binary 4U 1630-47 in the steep power law (or very high) state was observed and a linear polarization degree of the 2-8 keV X-rays of 6.8-7.2 % at a position angle of 21.3 +/- 0.9 East of North.

First detection of X-ray polarization from the accreting neutron star 4U 1820-303

A. Di Marco, +116 more
TL;DR: In this paper , the authors reported the first detection of polarization in the X-rays for atoll-source 4U 1820-303, obtained with the Imaging X-ray Polarimetry Explorer (IXPE) at 99.999% confidence level (CL).

A polarimetrically oriented X-ray stare at the accreting pulsar EXO 2030+375

Christian Malacaria, +104 more
TL;DR: In this paper , the authors report on the results of yet another XRP, EXO 2030+375, observed with IXPE and contemporarily monitored with Insight-HXMT and SRG/ART-XC.
Journal ArticleDOI

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

Alexander A. Mushtukov, +104 more
TL;DR: In this article , the authors presented the results of observations X Persei performed with the Imaging X-ray Polarimetry Explorer (IXPE) and found that the energy-averaged polarization degree in 3-8-kV band varied from several to ∼20-per-cent over the pulse with a phase dependence resembling the pulse profile.
