Long Term Variability of O VII Line Intensity toward the Lockman Hole Observed with Suzaku from 2006 to 2011
Hiroshi Yoshitake, Kazuhiro Sakai, Kazuhisa Mitsuda +3
Long-term time variabilities of the OVII (0.57 keV) emission in the soft X-ray diffuse background were studied using six Suzaku annual observations of blank sky towards the Lockman…
Enhancement of Terrestrial Diffuse X-ray Emission Associated With Coronal Mass Ejection and Geomagnetic Storm
Yuichiro Ezoe, Yoshizumi Miyoshi, Hiroshi Yoshitake +4
We present an analysis of a Suzaku observation taken during the geomagnetic storm of 2005 August 23-24. We found time variation of diffuse soft X-ray emission when a coronal mass e…
SUZAKU Observation of a New Merging Group of Galaxies at a Filamentary Junction
Hajime Kawahara, Hiroshi Yoshitake, Takahiro Nishimichi +1
We report on a new merging group of galaxies, Suzaku J1552+2739 at z ~ 0.08 revealed by a SUZAKU observation. The group was found by observing a junction of galaxy filaments optica…
Time Variability of the Geocoronal Solar Wind Charge Exchange in the Direction of the Celestial Equator
Yuichiro Ezoe, Ken Ebisawa, Noriko Y. Yamasaki +5
We report the detection of a time variable OVII line emission in a deep 100 ks Suzaku X-ray Imaging Spectrometer spectrum of the Galactic Ridge X-ray emission. The observed line in…
