New CTI Correction Method for the Spaced-Row Charge Injection of the Suzaku X-Ray Imaging Spectrometer
Hideki Uchiyama, Midori Ozawa, Hironori Matsumoto +21
The charge transfer inefficiency (CTI) of the X-ray CCDs on board the Suzaku satellite (X-ray Imaging Spectrometers; XIS) has increased since the launch due to radiation damage, an…
Energy-Scale Calibration of the Suzaku X-Ray Imaging Spectrometer Using the Checker Flag Charge Injection Technique in Orbit
Midori Ozawa, Hideki Uchiyama, Hironori Matsumoto +25
The X-ray Imaging Spectrometer (XIS) on board the Suzaku satellite is an X-ray CCD camera system that has superior performance such as a low background, high quantum efficiency, an…
Restoring the Suzaku Source Position Accuracy and Point-Spread Function
Yasunobu Uchiyama, Yoshitomo Maeda, Masatoshi Ebara +9
We present an empirical correction of sky coordinates of X-ray photons obtained with the XIS aboard the Suzaku satellite to improve the source position accuracy and restore the poi…
Monte-Carlo Simulator and Ancillary Response Generator of Suzaku XRT/XIS System for Spatially Extended Source Analysis
Y. Ishisaki, Y. Maeda, R. Fujimoto +31
We have developed a framework for the Monte-Carlo simulation of the X-Ray Telescopes (XRT) and the X-ray Imaging Spectrometers (XIS) onboard Suzaku, mainly for the scientific analy…
An Apparent Hard X-ray Decline of CH Cygni
Koji Mukai, Manabu Ishida, Caroline Kilbourne +4
CH Cygni is a symbiotic star consisting of an M giant and an accreting white dwarf, which is known to be a highly variable X-ray source with a complex, two-component, spectra. Here…
Suzaku Observations of HESS J1616-508: Evidence for a Dark Particle Accelerator
Hironori Matsumoto, Masaru Ueno, Aya Bamba +15
We observed the bright unidentified TeV gamma-ray source HESS J1616-508 with the X-ray Imaging Spectrometers onboard the Suzaku satellite. No X-ray counterpart was found to a limit…
