Understanding Pulsar Wind Nebulae with the SKA
Joseph D. Gelfand, C. -Y. Ng, B. Posselt +9
Produced by the interaction between the ``pulsar wind'' powered by the rotational energy of a neutron star and its surroundings, the study of pulsar wind nebulae (PWNe) provides vi…
A VLBA-resolved Jet Associated with Super-Eddington Accretion in a Radio-loud Quasar at
Sakiko Obuchi, Ingyin Zaw, Kazuhiro Hada +2
We report the detailed jet properties of eROSITA Final Equatorial Depth Survey (eFEDS) J084222.9+001000 (hereafter ID830), a radio-loud super-Eddington quasar at , reveal…
New Hard X-Ray and Multiwavelength Study of the PeVatron Candidate PWN G0.9+0.1 in the Galactic Center Region
Giulia Brunelli, Kaya Mori, Jaegeun Park +12
We present a new X-ray study and multiwavelength spectral energy distribution (SED) modeling of the young pulsar wind nebula (PWN) powered by the energetic pulsar PSR J1747-2809, i…

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…
Determining the nature of IC 10 X-2: A comprehensive study of the Optical/Infrared emission from an extragalactic BeHMXB
Jwaher Alnaqbi, Joseph D. Gelfand, Payaswini Saikia +7
We present a comprehensive analysis of the optical and infrared (IR) properties of high-mass X-ray binary (HMXB) IC 10 X-2, classified as a super-giant HMXB and super-fast X-ray tr…
