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…
A Physical Model of Pulsar X-ray Filaments
Jack T. Dinsmore, Roger W. Romani
We present a model for pulsar filaments - a class of narrow X-ray nebulae misaligned with the proper motion, powered by pulsar-generated . We suggest that cosmic ray-enhance…
Chandra Proper Motions and Milliarcsecond Astrometry of Nineteen Pulsars
Jack T. Dinsmore, Roger W. Romani
We present X-ray proper motion (PM) measurements of 19 pulsars using new and archival data from the Chandra X-ray Observatory, including pulsar wind trails and X-ray filaments. Pre…
X-ray Polarization of the Intrabinary Shock in Redback Pulsar J17232837
Andrew G. Sullivan, Jack T. Dinsmore, Roger W. Romani
The intrabinary shocks (IBS) in spider pulsars emit non-thermal synchrotron X-rays from accelerated electrons and positrons in the shocked pulsar wind, likely energized by magnetic…
Advanced Weights for IXPE Polarization Analysis
Jack T. Dinsmore, Roger W. Romani
As the Imaging X-ray Polarimetry Explorer (IXPE) measures increasingly faint sources, the need for precise polarimetry extraction becomes paramount. In addition to previously descr…
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,…
The Guitar's Magnetic Field Revealed by Starlight Polarization
Jack T. Dinsmore, Roger W. Romani
The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed…
A Catalog of Pulsar X-ray Filaments
Jack T. Dinsmore, Roger W. Romani
We present the first Chandra X-ray Observatory (CXO) catalog of "pulsar X-ray filaments," or "misaligned outflows." These are linear, synchrotron radiating features powered by ultr…
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…
Luminosity functions consistent with a pulsar-dominated Galactic Center Excess
Jack T. Dinsmore, Tracy R. Slatyer
A new population of millisecond pulsars is a long-standing proposed explanation for the excess of GeV-scale gamma rays emanating from the region surrounding the center of the Milky…
