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…
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…
Shedding New Light on the 3C 273 Jet with the Spitzer Space Telescope
Y. Uchiyama, C. M. Urry, C. C. Cheung +7
We have performed infrared imaging of the jet of the quasar 3C 273 at wavelengths 3.6 and 5.8 microns with the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. When com…
Spitzer IRAC Imaging of the Relativistic Jet from Superluminal Quasar PKS 0637-752
Y. Uchiyama, C. M. Urry, J. Van Duyne +5
Emission from the relativistic jet located at hundreds of kpc from the core of the superluminal quasar PKS 0637-752 was detected at 3.6 and 5.8 microns with the Infrared Array Came…
Nonthermal X-radiation of SNR RX J1713.7-3946: The Relations to a Nearby Molecular Cloud
Y. Uchiyama, F. A. Aharonian, T. Takahashi +3
The recent X-ray and CO observations of RX J1713.7-3946 show that a significant fraction of the nonthermal X-ray emission of this unique supernova remnant associates, in one way or…
Spectral properties of nonthermal X-ray emission from the shell-type SNR RX J1713.7-3946 as revealed by XMM-Newton
Junko S. Hiraga, Yasunobu Uchiyama, Tadayuki Takahashi +1
We present the results of our morphological and spectral study of properties of the supernova remnant RX J1713.7-3946 based on data obtained with XMM-Newton. Highly inhomogeneous s…
