IXPE detects 9.9% ± 2.5% 2-8 keV polarization from the Kes 75 PWN in one epoch, implying a toroidal field aligned with the symmetry axis, while the first epoch shows an anomalous pulse at phase 0.5 that suppresses phase-averaged polarization.

IXPE data on magnetar 1E 1547.0-5408 show high linear polarization from a small hot spot whose phase-dependent angle is fit by a rotating vector model, with a marginal energy-dependent dip in polarization degree that may indicate vacuum resonance but does not constitute compelling evidence for biref
Phase-resolved broadband spectropolarimetry of magnetar 1RXS J170849.0-400910 shows evolving pulse profiles, a blackbody plus two power-law spectrum, and polarization up to 64% consistent with magnetospheric pair-synchrotron emission.
Equatorial twist geometry in the magnetar magnetosphere allows resonant Compton upscattering to reproduce the hard X-ray spectrum of 4U 0142+61 with optical depth limits from resonant cooling.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.

Kes 75 with IXPE: Detection of Nebular X-ray Polarization and Change in Pulsar Lightcurve
IXPE detects 9.9% ± 2.5% 2-8 keV polarization from the Kes 75 PWN in one epoch, implying a toroidal field aligned with the symmetry axis, while the first epoch shows an anomalous pulse at phase 0.5 that suppresses phase-averaged polarization.
