Decadal brightening in the northeastern non-thermal filament of Cassiopeia A
Nao Kominato, Toshiki Sato, Yusuke Sakai +2
We present the decadal brightening of non-thermal emission flux in the northeastern filament of the young supernova remnant Cassiopeia A (Cas A), which highlights dynamic processes…
First Detection of X-ray Polarization and Its Short-term Increase Pre- and Post-Eclipse in HMXB 4U 1700-377
Kaito Ninoyu, Keisuke Uchiyama, Shinya Yamada +9
We report the first statistically significant detection of X-ray polarization from the high-mass X-ray binary (HMXB) 4U 1700-377, observed using the Imaging X-ray Polarimetry Explo…
Kinematics of Supernova Remnants Using Multiepoch Maximum Likelihood Estimation: Chandra Observation of Cassiopeia A as an Example
Yusuke Sakai, Shinya Yamada, Toshiki Sato +2
Decadal changes in a nearby supernova remnant (SNR) were analyzed using a multiepoch maximum likelihood estimation (MLE) approach. To achieve greater accuracy in capturing the dyna…
Few-electron highly charged muonic Ar atoms verified by electronic x rays
T. Okumura, T. Azuma, D. A. Bennett +40
Electronic x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra p…
