XRISM Pre-Pipeline and Singularity: Container-Based Data Processing for the X-Ray Imaging and Spectroscopy Mission and High-Performance Computing
Satoshi Eguchi, Makoto Tashiro, Yukikatsu Terada +20
The X-Ray Imaging and Spectroscopy Mission (XRISM) is the seventh Japanese X-ray observatory whose development and operation are in collaboration with universities and research ins…
Verification of the Timing System for the X-ray Imaging and Spectroscopy Mission in the GPS Unsynchronized Mode
Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato +59
We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is…
Development of the Timing System for the X-Ray Imaging and Spectroscopy Mission
Yukikatsu Terada, Megumi Shidatsu, Makoto Sawada +62
This paper describes the development, design, ground verification, and in-orbit verification, performance measurement, and calibration of the timing system for the X-Ray Imaging an…
Container-Based Pre-Pipeline Data Processing on HPC for XRISM
Satoshi Eguchi, Makoto Tashiro, Yukikatsu Terada +18
The X-Ray Imaging and Spectroscopy Mission (XRISM) is the 7th Japanese X-ray observatory, whose development and operation are in collaboration with universities and research instit…
NinjaSat: Astronomical X-ray CubeSat Observatory
Toru Tamagawa, Teruaki Enoto, Takao Kitaguchi +22
NinjaSat is an X-ray CubeSat designed for agile, long-term continuous observations of bright X-ray sources, with the size of 6U ( mm) and a mass of 8 kg.…
Characterization of more than three years of in-orbit radiation damage of SiPMs on GRBAlpha and VZLUSAT-2 CubeSats
Jakub Ripa, Marianna Dafcikova, Pavel Kosik +42
Silicon photomultipliers (SiPMs) are prone to radiation damage which causes an increase of dark count rate. This leads to an increase in low-energy threshold in a gamma-ray detecto…
The ASTRO-H X-ray Observatory
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +220
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
