Rapid Expansion of the Young Type Ia Supernova Remnant 0519-69.0: More Evidence for a Circumstellar Shell
Benson T. Guest, Kazimierz J. Borkowski, Parviz Ghavamian +5
The nature of Type Ia supernovae remains controversial. The youngest remnants of Ia supernovae hold clues to the explosion and to the immediate surroundings. We present a third epo…
A broadband X-ray study of the Rabbit pulsar wind nebula powered by PSR J1418-6058
Jaegeun Park, Chanho Kim, Jooyun Woo +4
We report on broadband X-ray properties of the Rabbit pulsar wind nebula (PWN) associated with the pulsar PSR J1418-6058 using archival Chandra and XMM-Newton data, and a new NuSTA…
X-ray studies of the pulsar PSR J1420-6048 and its TeV pulsar wind nebula in the Kookaburra region
Jaegeun Park, Chanho Kim, Jooyun Woo +4
We present a detailed analysis of broadband X-ray observations of the pulsar PSR J1420-6048 and its wind nebula (PWN) in the Kookaburra region with Chandra, XMM-Newton, and NuSTAR.…
An X-ray Proper Motion Study of the LMC SNR 0509-67.5
Benson T. Guest, Kazimierz J. Borkowski, Parviz Ghavamian +4
We present a third epoch of Chandra observations of the Type Ia Large Magellanic Cloud Supernova remnant (SNR) 0509-67.5. With these new observations from 2020, the baseline for pr…
Evidence for a Dense, Inhomogeneous Circumstellar Medium in the Type Ia SNR 0519-69.0
Brian J. Williams, Parviz Ghavamian, Ivo R. Seitenzahl +3
We perform an expansion study of the Balmer dominated outer shock of the SNR 051969.0 in the LMC by using a combination of new HST WFC3 imagery obtained in 2020 and archival ACS…
The Eel Pulsar Wind Nebula: a PeVatron-Candidate Origin for HAWC J1826-128 and HESS J1826-130
Daniel A. Burgess, Kaya Mori, Joseph D. Gelfand +8
HAWC J1826-128 is one of the brightest Galactic TeV gamma-ray sources detected by the High Altitude Water Cherenkov (HAWC) Observatory, with photon energies extending up to nearly…
