Richardson-Lucy deconvolution with a spatially Variant point-spread function of Chandra: Supernova Remnant Cassiopeia A as an Example
Yusuke Sakai, Shinya Yamada, Toshiki Sato +3
Richardson-Lucy (RL) deconvolution is one of the classical methods widely used in X-ray astronomy and other areas. Amid recent progress in image processing, RL deconvolution still…
Discovery of Stable Titanium at the Northeastern Jet of Cassiopeia A: Need for a Weak Jet Mechanism?
Takuma Ikeda, Yasunobu Uchiyama, Toshiki Sato +3
The origin of the jet-like structures observed in Cassiopeia A is still unclear, although it seems to be related to its explosion mechanism. X-ray observations of the characteristi…
On the origin of the asymmetry of the ejecta structure and explosion of G350.10.3
Tomoya Tsuchioka, Yasunobu Uchiyama, Ryota Higurashi +4
We present X-ray analysis of the ejecta of supernova remnant G350.10.3 observed with Chandra and Suzaku, and clarify the ejecta's kinematics over a decade and obtain a new obser…
X-ray Hotspots in the Northwest Shell of the Supernova Remnant RX J1713.73946
Ryota Higurashi, Naomi Tsuji, Yasunobu Uchiyama
The supernova remnant (SNR) RX J1713.73946 is one of the best-studied accelerators of cosmic rays because of its strong nonthermal X-ray and gamma-ray radiation. We have analyze…
NuSTAR observations of the supernova remnant RX J1713.73946
Naomi Tsuji, Yasunobu Uchiyama, Felix Aharonian +4
The shock waves of supernova remnants (SNRs) are prominent candidates for the acceleration of the Galactic cosmic rays. SNR RX J1713.73946 is one well-studied particle accelerat…
