Suzaku study on the Ejecta of the Supernova Remnant G272.23.2
Fumiyoshi Kamitsukasa, Katsuji Koyama, Hiroshi Nakajima +5
We report re-analyses of the Suzaku observations of the Galactic supernova remnant (SNR), G272.23.2, for which the previous studies were limited below 3 keV. With careful data r…
Evidence for Thermal X-Ray Line Emission from the Synchrotron-Dominated Supernova Remnant RX J1713.7-3946
Satoru Katsuda, Fabio Acero, Nozomu Tominaga +14
We report the first detection of thermal X-ray line emission from the supernova remnant (SNR) RX J1713.7-3946, the prototype of the small class of synchrotron dominated SNRs. A sof…
Kepler's Supernova: An Overluminous Type Ia Event Interacting with a Massive Circumstellar Medium at a Very Late Phase
Satoru Katsuda, Koji Mori, Keiichi Maeda +7
We have analyzed XMM-Newton, Chandra, and Suzaku observations of Kepler's supernova remnant (SNR) to investigate the properties of both the SN ejecta and the circumstellar medium (…
X-ray Fading and Expansion in the "Miniature Supernova Remnant" of GK Persei
D. Takei, J. J. Drake, H. Yamaguchi +3
We report on a second epoch of Chandra X-ray imaging spectroscopy of the spatially-resolved old nova remnant GK Persei. An ACIS-S3 observation of 97.4 ks was conducted in November…
