IXPE observation of the new magnetar source EP J223759.5+531421

Roberto Taverna, Lorenzo Marra, Roberto Turolla +9

We report on the detection of polarized X-ray emission from the new Galactic magnetar EP J223759.5+531421, discovered by the Einstein Probe Wide-field X-ray Telescope on 2026 June…

Magnetospheric birefringence breaks the rotating-vector model and depolarises X-ray pulsars

Alexander A. Mushtukov, Sergey S. Tsygankov, Silvia Zane +4

Accreting X-ray pulsars have long been expected to show large linear polarisation below the cyclotron resonance. In the standard picture, this follows from two facts: radiative opa…

EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics

Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137

The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…

A new NASA Pioneer: the Globe Orbiting Soft X-ray Polarimeter (GOSoX)

Herman L Marshall, Sarah N T Heine, Alan Garner +16

The Globe Orbiting Soft X-ray Polarimeter (GOSoX) is a spectropolarimeter for the soft X-ray band. GOSoX is based on the Rocket Experiment Demonstration of a Soft X-ray Polarimeter…

Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry

Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97

RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…

The long quest for vacuum birefringence in magnetars: 1E 1547.0-5408 and the elusive smoking gun

Roberto Taverna, Roberto Turolla, Lorenzo Marra +7

Magnetars are now known to be among the most strongly polarized celestial sources in X-rays. Here we report on the observation of the magnetar 1E 1547.0-5408 per…
