Broad-band High-Energy Resolution Hard X-ray Spectroscopy using Transition Edge Sensors at SPring-8
Shinya Yamada, Yuto Ichinohe, Hideyuki Tatsuno +40
We have succeeded in operating a transition-edge sensor (TES) spectrometer and evaluating its performance at the SPring-8 synchrotron X-ray light source. The TES spectrometer consi…
High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter
Misaki Mizumoto, Masahiro Tsujimoto, Renata S. Cumbee +11
The spectroscopic performance of x-ray instruments can be affected at high count rates. The effects and mitigation in the optical chain, such as x-ray attenuation filters or de-foc…
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…
MASTER OT J030227.28+191754.5: a dwarf nova at a massive oxygen-neon white-dwarf system ?
Mariko Kimura, Kazumi Kashiyama, Toshikazu Shigeyama +3
We present timing and spectral analysis results of the {\it NICER} and {\it NuSTAR} observations of the dwarf nova MASTER OT J030227.28191754.5 during the 2021--2022 outburst. T…
Absolute Energy Measurements with Superconducting Transition-Edge Sensors for Muonic X-ray Spectroscopy at 44 keV
Daikang Yan, Joel C. Weber, Tejas Guruswamy +25
Superconducting transition-edge sensor (TES) microcalorimeters have great utility in x-ray applications owing to their high energy resolution, good collecting efficiency and the fe…
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…
