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…
