IXPE Detection of Highly Polarized X-Rays from the Magnetar 1E 1841-045

The Astrophysical Journal Letters
The Imaging X-ray Polarimetry Explorer (IXPE) observed for the first time highly polarized X-ray emission from the magnetar 1E 1841−045, targeted after a burst-active phase in 2024 August.

X-ray polarimetry as a new method of studying X-ray binary systems [PDF]

This thesis investigates black hole X-ray binaries through multi-instrument observational data, focusing on spectral and polarimetric analysis. These systems, in which a black hole accretes matter from a companion star, serve as laboratories for studying

Graph neural networks trained on null signal for angle reconstruction in x-ray polarimetry

Machine Learning: Science and Technology
Scientific real detectors often produce sparse, irregular data defined on non-Euclidean domains, where conventional convolutional neural networks (CNNs) impose geometric biases that distort physical observables. In x-ray polarimetry, such distortions can
