Study of the Spectral and Temporal Characteristics of X-Ray Emission of the Gamma-Ray Binary LS 5039 with Suzaku
T. Takahashi, T. Kishishita, Y. Uchiyama +6
We report on the results from Suzaku broadband X-ray observations of the galactic binary source LS5039. The Suzaku data, which have continuous coverage of more than one orbital per…
Emission from Large-scale Jets in Quasars
Yasunobu Uchiyama
We consider the emission processes in the large-scale jets of powerful quasars based on the results obtained with the VLA, Spitzer, Hubble, and Chandra. We show that two well-known…
Study of Nonthermal Emission from SNR RX J1713.7-3946 with Suzaku
Takaaki Tanaka, Yasunobu Uchiyama, Felix A. Aharonian +11
We present results obtained from a series of observations of the supernova remnant RX J1713.7-3946 by the Suzaku satellite. The observations cover about two-thirds of the remnant s…
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…
Fast Variability of Nonthermal X-Ray Emission in Cassiopeia A: Probing Electron Acceleration in Reverse-Shocked Ejecta
Yasunobu Uchiyama, Felix Aharonian
Recent discovery of the year-scale variability in the synchrotron X-ray emission of the supernova remnant (SNR) RX J1713.7-3946 has initiated our study of multi-epoch X-ray images…
