A Deep Chandra Observation of the Oxygen-Rich Supernova Remnant 0540-69.3 in the Large Magellanic Cloud
Sangwook Park, John P. Highes, Patrick O. Slane +2
Using our deep ~120 ks Chandra observation, we report on the results from our spatially-resolved X-ray spectral analysis of the "oxygen-rich" supernova remnant (SNR) 0540-69.3 in t…
Chandra Observations of WR147 Reveal a Double X-ray Source
Svetozar A. Zhekov, Sangwook Park
We report the first results from deep X-ray observations of the Wolf-Rayet binary system WR147 with the Chandra HETG. Analysis of the zeroth order data reveals that WR147 is a doub…
High Resolution X-ray Imaging of Supernova Remnant 1987A
C. -Y. Ng, B. M. Gaensler, S. S. Murray +5
We report observations of the remnant of Supernova 1987A with the High Resolution Camera (HRC) onboard the Chandra X-ray Observatory. A direct image from the HRC resolves the annul…
X-ray Evolution of SNR 1987A: The Radial Expansion
Judith L. Racusin, Sangwook Park, Svetozar Zhekov +3
We present the evolution of the radial expansion of SNR 1987A as measured using Chandra X-ray observations taken over the last 10 years. To characterize the complex structure of th…
Spitzer Spectroscopy of the Galactic Supernova Remnant G292.0+1.8: Structure and Composition of the Oxygen-Rich Ejecta
Parviz Ghavamian, John C. Raymond, William P. Blair +4
We present mid-infrared (5-40 micron) spectra of shocked ejecta in the Galactic oxygen-rich supernova remnant G292.0+1.8, acquired with the IRS spectrograph on board the Spitzer Sp…
