The Cold Dust Content of the Oxygen-Rich Supernova Remnant G292.0+1.8
Parviz Ghavamian, Brian J. Williams
We present far-infrared images of the Galactic oxygen-rich supernova remnant (SNR) G292.0+1.8, acquired with the PACS and SPIRE instruments of the Herschel Space Observatory. We fi…
An X-ray and Radio Study of the Varying Expansion Velocities in Tycho's Supernova Remnant
Brian J. Williams, Laura Chomiuk, John W. Hewitt +5
We present newly obtained X-ray and radio observations of Tycho's supernova remnant using {\it Chandra} and the Karl G. Jansky Very Large Array in 2015 and 2013/14, respectively. W…
The Refined Shock Velocity of the X-Ray Filaments in the RCW 86 Northeast Rim
Hiroya Yamaguchi, Satoru Katsuda, Daniel Castro +5
A precise measurement of shock velocities is crucial for constraining the mechanism and efficiency of cosmic-ray (CR) acceleration at supernova remnant (SNR) shock fronts. The nort…
