Examining Neutrino-Matter Interactions in the Cassiopeia A Supernova
Toshiki Sato, Takashi Yoshida, Hideyuki Umeda +4
Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confi…
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…
A broadband X-ray imaging spectroscopy in the 2030s: the FORCE mission
Koji Mori, Takeshi G. Tsuru, Kazuhiro Nakazawa +49
In this multi-messenger astronomy era, all the observational probes are improving their sensitivities and overall performance. The Focusing on Relativistic universe and Cosmic Evol…
The 3-D X-ray Ejecta Structure of Tycho's Supernova Remnant
Matthew J. Millard, Sangwook Park, Toshiki Sato +5
We present our velocity measurements of 59 clumpy, metal-rich ejecta knots in the supernova remnant (SNR) of SN 1572 (Tycho). We use our 450 ks Chandra High Energy Transmission Gra…
X-ray Studies of the Inverted Ejecta Layers in the Southeast Area of Cassiopeia A
Tomoya Tsuchioka, Toshiki Sato, Shinya Yamada +1
The central strong activities in core-collapse supernovae expect to produce the overturning of the Fe- and Si/O-rich ejecta during the supernova explosion based on multi-dimensiona…
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…
