Discovery of Enhanced Radiative Recombination Continua of He-like Iron and Calcium from IC 443 and Its Implications
Takao Ohnishi, Hiroyuki Uchida, Takeshi Go Tsuru +3
We present deep observations of the Galactic supernova remnant IC 443 with the {\it Suzaku X-ray satellite}. We find prominent K-shell lines from iron and nickel, together with a t…
Recombining Plasma and Hard X-ray Filament in the Mixed-Morphology Supernova Remnant W44
Hiroyuki Uchida, Katsuji Koyama, Hiroya Yamaguchi +6
We report new features of the typical mixed-morphology (MM) supernova remnant (SNR) W44. In the X-ray spectra obtained with Suzaku, radiative recombination continua (RRCs) of highl…
New Insights into SNR Evolution Revealed by the Discovery of Recombining Plasmas
Hiroya Yamaguchi, Midori Ozawa, Takao Ohnishi
We report the discovery of recombining plasmas in three supernova remnants (SNRs) with the Suzaku X-ray astronomy satellite. During SNR's evolution, the expanding supernova ejecta…
X-Ray Spectrum of a Peculiar Supernova Remnant G359.1-0.5
Takao Ohnishi, Katsuji Koyama, Takeshi Go Tsuru +3
We present the Suzaku results of a supernova remnant (SNR), G359.1-0.5 in the direction of the Galactic center region. From the SNR, we find prominent K-shell lines of highly ioniz…
