High-Resolution X-ray Spectroscopy of SNR 1987A: Chandra LETG and HETG Observations in 2007
Svetozar A. Zhekov, Richard McCray, Daniel Dewey +4
We present an extended analysis of the deep Chandra LETG and HETG observations of the supernova remnant 1987A (SNR 1987A) carried out in 2007. The global fits to the grating spectr…
Supernova Remnant 1987A: High Resolution Images and Spectrum from Chandra Observations
Sangwook Park, Svetozar A. Zhekov, David N. Burrows +3
We report on the morphological and spectral evolution of SNR 1987A from the monitoring observations with the Chandra/ACIS. As of 2005, the X-ray-bright lobes are continuously brigh…
Discovery of Outlying, High-Velocity Oxygen-Rich Ejecta in Cassiopeia A
R. A. Fesen, M. C. Hammell, J. Morse +7
Hubble Space Telescope images of the young Galactic supernova remnant Cassiopeia A reveal a far larger population of outlying, high-velocity knots of ejecta with a broader range of…
Chandra Observations of Shock Kinematics in Supernova Remnant 1987A
S. A. Zhekov, R. McCray, K. J. Borkowski +2
We report the first results from deep X-ray observations of the SNR 1987A with the Chandra LETG. Temperatures inferred from line ratios range from 0.1 - 2 keV and increase with ion…
Discovery of a New Pulsar Wind Nebula in the Large Magellanic Cloud
B. M. Gaensler, S. P. Hendrick, S. P. Reynolds +1
We present new high-resolution radio and X-ray observations of the supernova remnant (SNR) B0453-685 in the Large Magellanic Cloud, carried out with the Australia Telescope Compact…
Thermal X-ray emission from shocked ejecta in Type Ia Supernova Remnants. Prospects for explosion mechanism identification
Carles Badenes, Eduardo Bravo, Kazimierz J. Borkowski +1
The explosion mechanism behind Type Ia supernovae is a matter of continuing debate. The diverse attempts to identify or at least constrain the physical processes involved in the ex…
