A Suzaku Observation of the Low-Ionization Fe-Line Emission from RCW 86
Masaru Ueno, Rie Sato, Jun Kataoka +14
The newly operational X-ray satellite Suzaku observed the southwestern quadrant of the supernova remnant (SNR) RCW 86 in February 2006 to study the nature of the 6.4 keV emission l…
X-ray emission from a merger remnant, NGC 7252,the "Atoms-for-Peace" galaxy
Hisamitsu Awaki, Hironori Matsumoto, Hiroshi Tomida
We observed a nearby merger remnant NGC 7252 with the X-ray satellite ASCA, and detected X-ray emission with the X-ray flux of (1.8+/-0.3)E-13 ergs/s/cm/cm in the 0.5 - 10 keV band…
Discovery of Non-Thermal X-Rays from the Shell of RCW86
Aya Bamba, Katsuji Koyama, Hiroshi Tomida
We report the ASCA (Advanced Satellite for Cosmology and Astrophysics) results of RCW 86, a shell-like supernova remnant (SNR). The bright region in the X-ray band traces the radio…
ICM masses in nearby and distant clusters of galaxies
Takeshi Go Tsuru, Hironobu Matsumoto, Katsuji Koyama +4
We compile X-ray data of clusters of galaxies at a wide range of redshift and compare X-ray luminosities, gas masses, iron abundances and iron masses of nearby clust…
