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…

The X-ray synchrotron rims in Cassiopeia A narrow with energy

Adrien Picquenot, Brian J. Williams, Fabio Acero +1

Some young supernova remnants exhibit thin filaments of X-ray synchrotron radiation coinciding with the forward shock due to accelerated electrons interacting with the local magnet…

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…

Locating the CSM Emission within the Type Ia Supernova Remnant N103B

Benson T. Guest, William P. Blair, Kazimierz J. Borkowski +9

We present results from deep Chandra observations of the young Type Ia supernova remnant (SNR) 0509-68.7, also known as N103B, located in the Large Magellanic cloud (LMC). The remn…

Revealing Hidden Variability in PWNe With Spectral Index Maps

Benson Guest, Samar Safi-Harb

Pulsar wind nebulae (PWNe) are the synchrotron bubbles inflated by the rotational energy of a neutron star. Observing variability within them has previously been limited to cases o…

A Radio Continuum and Polarisation Study of the pulsar wind nebula CTB87 (G74.9+1.2)

R. Kothes, W. Reich, S. Safi-Harb +3

We present radio continuum and linear polarisation observations of the pulsar wind nebula CTB87 (G74.9+1.2) with the Effelsberg 100-m radio telescope between 4.75 and 32 GHz. An an…
