Evidence for Thermal X-Ray Line Emission from the Synchrotron-Dominated Supernova Remnant RX J1713.7-3946
Satoru Katsuda, Fabio Acero, Nozomu Tominaga +14
We report the first detection of thermal X-ray line emission from the supernova remnant (SNR) RX J1713.7-3946, the prototype of the small class of synchrotron dominated SNRs. A sof…
The Search for >35 MeV Neutrons from the June 3, 2012 Impulsive Flare
K. Koga, S. Masuda, H. Matsumoto +5
We analyzed a highly impulsive solar flare observed on June 3, 2012. In association with this flare, emissions of hard X-rays, high-energy gamma rays, and neutrons were detected by…
Nuclear Composition of Magnetized GRB Jets
Sanshiro Shibata, Nozomu Tominaga
We investigate the fraction of metal nuclei in the relativistic jets of gamma-ray bursts associated with core-collapse supernovae. We simulate the fallback in jet-induced explosion…
An emergence of new polarized emission region in blazar Mrk 421 associated with X-ray flare
Ryosuke Itoh, Yasushi Fukazawa, Yasuyuki T. Tanaka +8
We report on long-term multi-wavelength monitoring of blazar Mrk~421 from 2010 to 2011. The source exhibited extreme X-ray flares in 2010. Our research group performed optical phot…
