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

The paper presents a conceptual design for a stacked focal-plane polarimeter using multilayer mirrors, imaging photoelectric detectors, and an active Compton polarimeter to extend X-ray polarimetry to tens of keV with improved sensitivity.
