A Comprehensive X-ray Characterization of the Pulsar Wind Nebula CTB 87: Evidence for Reverse-Shock Interaction from Its X-ray and Broadband Emissions
Jaegeun Park, Jason Alford, Hongjun An +4
We present a comprehensive X-ray study of the pulsar wind nebula (PWN) CTB 87, utilizing new NuSTAR observations and archival Chandra and XMM-Newton data. Our joint analysis reveal…
Chandra X-ray Observations of the Pulsar Wind Nebula within CTA 1
Seth Gagnon, Oleg Kargaltsev, Jason Alford +2
We present deep Chandra observations of the pulsar wind nebula (PWN) powered by PSR J0007+7303 in the composite supernova remnant CTA 1. The merged ACIS image shows a je…
Detection of Diffuse Radio Emission inside the Supernova Remnant G338.3-0.0 associated with the Gamma-ray Source HESS J1640-465
Moaz Abdelmaguid, Joseph Gelfand, Jason Alford
We report the discovery of diffuse radio emission within SNR G338.3-0.0 using new MeerKAT observations at 816 MHz and 1.4 GHz. The radio emission spatially overlaps with the X-ray…
The Timing Evolution of the Magnetar Swift J1818.0-1607 During a Period of Reduced Activity
Moaz Abdelmaguid, Paulo C. C. Freire, Joseph D. Gelfand +3
We report results from an observational campaign of the radio-loud magnetar Swift J1818.0-1607 using the Green Bank Telescope (GBT) at 2.0 GHz, which began in November 2021 during…
NuSTAR and XMM-Newton Observations of PSR J1930+1852 and Its Pulsar Wind Nebula
J. A. J. Alford, G. -B. Zhang, J. D. Gelfand
Synchrotron X-ray emission from a pulsar wind nebula (PWN) is a sensitive probe of its magnetic field and high-energy particle population. Here we analyze contemporaneous NuSTAR an…
The High Energy X-ray Probe (HEX-P): Studying Extreme Accretion with Ultraluminous X-ray Sources
Matteo Bachetti, Matthew J. Middleton, Ciro Pinto +25
Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of po…
The High Energy X-ray Probe (HEX-P): Supernova remnants, pulsar wind nebulae, and nuclear astrophysics
Stephen Reynolds, Hongjun An, Moaz Abdelmaguid +29
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ( full width at half maximum) and broad spectral coverage (0.2--80 keV) with an…
The High Energy X-ray Probe (HEX-P): Sensitive broadband X-ray observations of transient phenomena in the 2030s
Murray Brightman, Raffaella Margutti, Ava Polzin +13
HEX-P will launch at a time when the sky is being routinely scanned for transient gravitational wave, electromagnetic and neutrino phenomena that will require the capabilities of a…
The High Energy X-ray Probe (HEX-P): Galactic PeVatrons, star clusters, superbubbles, microquasar jets, and gamma-ray binaries
Kaya Mori, Stephen Reynolds, Hongjun An +32
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging (<10" FWHM) and broad spectral coverage (0.2-80 keV) with an effective area far super…
The High Energy X-ray Probe (HEX-P): Magnetars and Other Isolated Neutron Stars
J. A. J. Alford, G. A. Younes, Z. Wadiasingh +23
The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding th…
