Discovery of the recombining plasma in the south of the Galactic center; a relic of the past Galactic center activity?
S. Nakashima, M. Nobukawa, H. Uchida +5
We report Suzaku results for soft X-ray emission to the south of the Galactic center (GC). The emission (hereafter "GC South") has an angular size of ~42' x 16' centered at (l, b)…
Asymmetric Ejecta Distribution in SN 1006
Hiroyuki Uchida, Hiroya Yamaguchi, Katsuji Koyama
We present the results from deep X-ray observations (~400 ks in total) of SN 1006 by the X-ray astronomy satellite Suzaku. The thermal spectrum from the entire supernova remnant (S…
Dynamics of X-Ray-Emitting Ejecta in the Oxygen-Rich Supernova Remnant Puppis A Revealed by the XMM-Newton RGS
Satoru Katsuda, Yutaka Ohira, Koji Mori +4
Using the unprecedented spectral resolution of the reflection grating spectrometer (RGS) onboard XMM-Newton, we reveal dynamics of X-ray--emitting ejecta in the oxygen-rich superno…
