Supernova remnants: Types and evolution
Aya Bamba, Brian J. Williams
Although only a small fraction of stars end their lives as supernovae, all supernovae leave behind a supernova remnant (SNR), an expanding shock wave that interacts with the surrou…
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…
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…
