Title: Doppler Velocities of X-ray Knots and Filaments in the Large Magellanic Cloud Supernova Remnant N132D

Abstract: The oxygen-rich supernova remnant N132D in the Large Magellanic Cloud was observed with the High Energy Transmission Grating Spectrometer onboard the Chandra X-ray Observatory. Individual emission lines of oxygen, neon, magnesium, and silicon are observed and Doppler shifts have been measured. We find Doppler velocities of knots and filaments of only a few hundred km/s supporting previous abundance studies that concluded that the X-ray emission is mostly swept-up ISM and not ejecta.
