Solar-type Magnetic Reconnection Model for Magnetar Giant Flare
Youhei Masada, Shigehiro Nagataki, Kazunari Shibata +1
We present a theoretical model describing magnetar giant flares on the basis of solar flare/coronal mass ejection theory. In our model, a preflare activity plays a crucial role in…
GEOTAIL observation of the SGR1806-20 Giant Flare: The first 600 ms
Toshio Terasawa, Yasuyuki Tanaka, Yasuhiro Takei +14
On December 27, 2004, plasma particle detectors on the GEOTAIL spacecraft detected an extremely strong signal of hard X-ray photons from the giant flare of SGR1806-20, a magnetar c…
A Spatial and Spectral Study of Nonthermal Filaments in Historical Supernova Remnants: Observational Results with Chandra
Aya Bamba, Ryo Yamazaki, Tatsuo Yoshida +2
The outer shells of young supernova remnants (SNRs) are the most plausible acceleration sites of high-energy electrons with the diffusive shock acceleration (DSA) mechanism. We stu…
Constraints On the Diffusive Shock Acceleration From the Nonthermal X-ray Thin Shells In SN1006 NE Rim
Ryo Yamazaki, Tatsuo Yoshida, Toshio Terasawa +2
Characteristic scale lengths of nonthermal X-rays from the SN1006 NE rim, which are observed by Chandra, are interpreted in the context of the diffusive shock acceleration on the a…
