Kes 75 with IXPE: Detection of Nebular X-ray Polarization and Change in Pulsar Lightcurve
Josephine Wong, Jack T. Dinsmore, Roger W. Romani +16
We present the first X-ray polarization measurements of the PSR/PWN complex within SNR Kes 75. Two IXPE observations were conducted in October/November 2024 a…
IXPE Polarizations of the Lighthouse Pulsar, Trail, and Filament
Jack T. Dinsmore, Roger W. Romani, S. Zhang +9
The Lighthouse pulsar (PSR J11016101) sports a bright X-ray trail and filament. The synchrotron emission from both structures is expected to be polarized, with electric vector p…
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…
In-flight performance of the IXPE telescopes
Riccardo Ferrazzoli, Enrico Costa, Sergio Fabiani +15
We present a comprehensive characterization of the on-orbit imaging performance of the three telescopes on board the Imaging X-ray Polarimetry Explorer (IXPE). Each telescope compr…
X-ray Polarization Detection of the Pulsar Wind Nebula in G21.5-0.9 with IXPE
Niccolò Di Lalla, Nicola Omodei, Niccolò Bucciantini +98
We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023,…
Mitigating Polarization Leakage in Gas Pixel Detectors through Hybrid Machine Learning and Analytic Event Reconstruction
Nicoló Cibrario, Michela Negro, Raffaella Bonino +18
Spatially resolved polarization measurements of extended X-ray sources are expanding our understanding of the emission mechanisms and magnetic field properties involved. Such measu…
