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…
Exploring the spin dependence on mass inclination and distance for the newly discovered black hole X-ray binary Swift J151857.0-572147
Yujia Song, James F. Steiner, Tong Zhao +7
The black hole X-ray binary (BHXRB) Swift J151857.0-572147 was discovered during its first outburst in March 2024. We review the archive of NICER observations from this outburst, f…
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,…
A polarized view of the young Pulsar Wind Nebula 3C 58 with IXPE
N. Bucciantini, J. Wong, R. W. Romani +11
Pulsar Wind nebulae (PWNe), are among the most efficient particle accelerators in the Universe, however understanding the physical conditions and the magnetic geometry in their inn…
Analysis of Crab X-ray Polarization using Deeper IXPE Observations
Josephine Wong, Tsunefumi Mizuno, Niccoló Bucciantini +98
We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in…
First detection of polarization in X-rays for PSR B0540-69 and its nebula
Fei Xie, Josephine Wong, Fabio La Monaca +100
We report on X-ray polarization measurements of the extra-galactic Crab-like PSR B0540-69 and its Pulsar Wind Nebula (PWN) in the Large Magellanic Cloud (LMC), using a ~850 ks Imag…
The Polarized Cosmic Hand: IXPE Observations of PSR B1509-58/MSH 15-52
Roger W. Romani, Josephine Wong, Niccolo Di Lalla +99
We describe IXPE polarization observations of the Pulsar Wind Nebula (PWN) MSH15-52, the `Cosmic Hand'. We find X-ray polarization across the PWN, with B field vectors generally al…
Improved Measurements of the IXPE Crab Polarization
Josephine Wong, Roger W. Romani, Jack T. Dinsmore
X-ray polarization from the Imaging X-ray Polarimetry Explorer (IXPE) provides an important new probe of the geometry of the pulsar emission zone and of particle acceleration in th…
Simultaneous space and phase resolved X-ray polarimetry of the Crab Pulsar and Nebula
Niccolò Bucciantini, Riccardo Ferrazzoli, Matteo Bachetti +93
The Crab pulsar and its nebula are among the most studied astrophysical systems, and constitute one of the most promising environments where high energy processes and particle acce…
