Imaging reconstruction method on X-ray data of CMOS polarimeter combined with coded aperture
Tsubasa Tamba, Hirokazu Odaka, Taihei Watanabe +7
X-ray polarization is a powerful tool for unveiling the anisotropic characteristics of high-energy celestial objects. We present a novel imaging reconstruction method designed for…
Measurement of Temperature Relaxation in the Postshock Plasma of the Northwestern Limb of SN 1006
Masahiro Ichihashi, Aya Bamba, Yuichi Kato +5
Heating of charged particles via collisionless shocks, while ubiquitous in the universe, is an intriguing yet puzzling plasma phenomenon. One outstanding question is how electrons…
Three-Dimensional Velocity Diagnostics to Constrain the Type Ia Origin of Tycho's Supernova Remnant
Hiroyuki Uchida, Tomoaki Kasuga, Keiichi Maeda +3
While various methods have been proposed to disentangle the progenitor system for Type Ia supernovae, their origin is still unclear. Circumstellar environment is a key to distingui…
Spatially Resolved RGS Analysis of Kepler's Supernova Remnant
Tomoaki Kasuga, Jacco Vink, Satoru Katsuda +4
The distribution and kinematics of the circumstellar medium (CSM) around a supernova remnant (SNR) tell us useful information about the explosion of its natal supernova (SN). Keple…
Artifact-less Coded Aperture Imaging in the X-ray Band with Multiple Different Random Patterns
Tomoaki Kasuga, Hirokazu Odaka, Kosuke Hatauchi +7
The coded aperture imaging technique is a useful method of X-ray imaging in observational astrophysics. However, the presence of imaging noise or so-called artifacts in a decoded i…
Asymmetric Expansion of the Fe ejecta in Kepler's Supernova Remnant
Tomoaki Kasuga, Toshiki Sato, Koji Mori +2
The ejecta kinematics of supernova remnants (SNRs) is one of crucial clues to understand the explosion mechanism of type Ia supernovae (SNe). In particular, the kinematic asymmetry…
