IXPE observation of PKS 2155-304 reveals the most highly polarized blazar

Pouya M. Kouch, Ioannis Liodakis, Riccardo Middei +133

We report the X-ray polarization properties of the high-synchrotron-peaked (HSP) blazar PKS 2155304 based on observations with the Imaging X-ray Polarimetry Explorer (IXPE). We…

Pulsar-wind-nebula-powered Galactic center X-ray filament G0.13-0.11: Proof of the synchrotron nature by IXPE

Eugene Churazov, Ildar Khabibullin, Thibault Barnouin +103

We report the discovery of X-ray polarization from the X-ray-bright filament. G0.13-0.11 in the Galactic center (GC) region. This filament features a bright, hard X-ray source that…

Discovery of strongly variable X-ray polarization in the neutron star low-mass X-ray binary transient XTE J1701462

Massimo Cocchi, Andrea Gnarini, Sergio Fabiani +105

After about 16 years since its first outburst, the transient neutron star low-mass X-ray binary XTE J1701462 turned on again in September 2022, allowing for the first study of i…

Complex variations of X-ray polarization in the X-ray pulsar LS V +44 17/RX J0440.9+4431

Victor Doroshenko, Juri Poutanen, Jeremy Heyl +109

We report on Imaging X-ray polarimetry explorer (IXPE) observations of the Be-transient X-ray pulsar LS V +44 17/RX J0440.9+4431 made at two luminosity levels during the giant outb…

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

Christian Malacaria, Jeremy Heyl, Victor Doroshenko +104

Accreting X-ray pulsars (XRPs) are presumably ideal targets for polarization measurements, as their high magnetic field strength is expected to polarize the emission up to a polari…

X-ray pulsar GRO J100857 as an orthogonal rotator

Sergey S. Tsygankov, Victor Doroshenko, Alexander A. Mushtukov +99

X-ray polarimetry is a unique way to probe the geometrical configuration of highly magnetized accreting neutron stars (X-ray pulsars). GRO J100857 is the first transient X-ray p…

Polarized x-rays constrain the disk-jet geometry in the black hole x-ray binary Cygnus X-1

Henric Krawczynski, Fabio Muleri, Michal Dovčiak +111

A black hole x-ray binary (XRB) system forms when gas is stripped from a normal star and accretes onto a black hole, which heats the gas sufficiently to emit x-rays. We report a po…

Polarized x-rays from a magnetar

Roberto Taverna, Roberto Turolla, Fabio Muleri +93

We report on the first detection of linearly polarized x-ray emission from an ultra-magnetized neutron star with the Imaging X-ray Polarimetry Explorer (IXPE). The IXPE 35 observat…
