Cosmic Ray Acceleration at the Forward Shock in Tycho's Supernova Remnant: Evidence from Chandra X-ray Observations
J. S. Warren, J. P. Hughes, C. Badenes +7
We present evidence for cosmic ray acceleration at the forward shock in Tycho's supernova remnant (SNR) from three X-ray observables: (1) the proximity of the contact discontinuity…
A Million-Second Chandra View of Cassiopeia A
Una Hwang, J. Martin Laming, Carles Badenes +20
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW count…
Raising the Dead: Clues to Type Ia Supernova Physics from the Remnant 0509-67.5
Jessica S. Warren, John P. Hughes
We present Chandra X-ray observations of the young supernova remnant (SNR) 0509-67.5 in the Large Magellanic Cloud (LMC), believed to be the product of a Type Ia supernova (SN Ia).…
Detection of Magnesium-Rich Ejecta in the Middle-Aged Supernova Remnant N49B
Sangwook Park, John P. Hughes, Patrick O. Slane +4
The middle-aged supernova remnant (SNR) N49B in the Large Magellanic Cloud has been observed with the {\it Chandra X-Ray Observatory}. The superb angular resolution of {\it Chandra…
