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…
Expansion Velocity of Ejecta in Tycho's Supernova Remnant Measured by Doppler Broadened X-ray Line Emission
Asami Hayato, Hiroya Yamaguchi, Toru Tamagawa +10
We show that the expansion of ejecta in Tycho's supernova remnant (SNR) is consistent with a spherically symmetric shell, based on Suzaku measurements of the Doppler broadened X-ra…
Suzaku Discovery of the Strong Radiative Recombination Continuum of Iron from the Supernova Remnant W49B
Midori Ozawa, Katsuji Koyama, Hiroya Yamaguchi +2
We present a hard X-ray spectrum of unprecedented quality of the Galactic supernova remnant W49B obtained with the Suzaku satellite. The spectrum exhibits an unusual structure cons…
Discovery of Strong Radiative Recombination Continua from The Supernova Remnant IC 443 with Suzaku
Hiroya Yamaguchi, Midori Ozawa, Katsuji Koyama +4
We present the Suzaku spectroscopic study of the Galactic middle-aged supernova remnant (SNR) IC 443. The X-ray spectrum in the 1.75-6.0 keV band is described by an optically-thin…
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant
A. Furuzawa, D. Ueno, A. Hayato +13
We use \suzaku observations to measure the spatial variation of the Fe K line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a…
