X-Ray Polarized View on the Accretion Geometry in the X-Ray Binary Circinus X-1
John Rankin, Fabio La Monaca, Alessandro Di Marco +101
Cir X-1 is a neutron star X-ray binary characterized by strong variations in flux during its eccentric 16.6 days orbit. There are also strong variations in the spectral state…
Soft X-ray Energy Spectra in the Wide-Field Galactic Disk Area Revealed with HaloSat
Kazuki Ampuku, Ikuyuki Mitsuishi, Koki Sakuta +3
We analyzed data from HaloSat observations for five fields in the Galactic disk located far away from the Galactic center (135 254) to understand th…
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…
X-ray Polarization of the Eastern Lobe of SS 433
Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri +103
How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that…
X-ray Polarization Reveals the Precessions of the Neutron Star in Hercules X-1
Jeremy Heyl, Victor Doroshenko, Denis González-Caniulef +100
In an accreting X-ray pulsar, a neutron star accretes matter from a stellar companion through an accretion disk. The high magnetic field of the rotating neutron star disrupts the i…
The detection of polarized x-ray emission from the magnetar 1E 2259+586
Jeremy Heyl, Roberto Taverna, Roberto Turolla +98
We report on IXPE, NICER and XMM-Newton observations of the magnetar 1E 2259+586. We find that the source is significantly polarized at about or above 20% for all phases except for…
