Suzaku X-Ray Imaging and Spectroscopy of Cassiopeia A
Y. Maeda, Y. Uchiyama, A. Bamba +26
Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, includi…
X-Ray Studies of HESS J1809-193 with Suzaku
Takayasu Anada, Aya Bamba, Ken Ebisawa +1
Suzaku observed the region including HESS J1809-193, one of the TeV unidentified (unID) sources, and confirmed existence of the extended hard X-ray emission previously reported by…
Chandra View of Pulsar Wind Nebula Tori
Aya Bamba, Koji Mori, Shinpei Shibata
The results from a systematic study of eleven pulsar wind nebulae with a torus structure observed with the Chandra X-ray observatory are presented. A significant observational corr…
The discovery of a pulsar wind nebula around the magnetar candidate AXP 1E1547.0-5408
Jacco Vink, Aya Bamba
We report the detection of extended emission around the anomalous X-ray pulsar AXP 1E1547.0-5408 using archival data of the Chandra X-ray satellite. The extended emission consists…
Particle Propagation in the Galactic Center and Spatial Distribution of Non-Thermal X-rays
Vladimir Dogiel, Dmitrii Chernyshov, Takayuki Yuasa +9
We showed that if the non-thermal emission from the Galactic center in the range 14-40 keV is due to inverse bremsstrahlung emission of subrelativistic protons, their interactions…
Search for Sc-K line emission from RX J0852.0--4622 Supernova remnant with Suzaku
Junko S. Hiraga, Y. Kobayashi, T. Tamagawa +6
We searched for evidence of line emission around 4keV from the northwestern rim of the supernova remnant RX J0852.0-4622 using Suzaku XIS data. Several papers have reported the det…
Line and Continuum Emission from the Galactic Center. III. Origin of 6.4 keV Line Emission from Molecular Clouds in the Galactic Center
Vladimir Dogiel, Kwong-Sang Cheng, Dmitrii Chernyshov +8
We analyze the 6.4 keV line and continuum emission from the molecular cloud Sgr B2 and the source HESS J1745-303, which is supposed to be a complex of molecular gas. From the HESS…
An Antarctic ice core recording both supernovae and solar cycles
Yuko Motizuki, Kazuya Takahashi, Kazuo Makishima +8
Ice cores are known to be rich in information regarding past climates, and the possibility that they record astronomical phenomena has also been discussed. Rood et al. were the fir…
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant
A. Furuzawa, D. Ueno, A. Hayato +13
We use \suzaku observations to measure the spatial variation of the Fe K line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a…
