Gamma-Ray and AntiMatter Survey(GRAMS) experiment
J. Zeng, T. Aramaki, D. Ames +62
The Gamma-Ray and AntiMatter Survey (GRAMS) is a next-generation experiment using a Liquid Argon Time Projection Chamber (LArTPC) detector to measure MeV gamma rays and antiparticl…
Pile-up simulator for XRISM/Xtend onboard the X-ray Imaging and Spectroscopy Mission (XRISM)
Tomokage Yoneyama, Tsubasa Tamba, Hirokazu Odaka +6
In X-ray astronomy, most observatories utilize multi-pixel photon-counting devices. When a photon counting device observes a bright source, we face an unavoidable problem called pi…
High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter: II. Energy scale and resolution in orbit
Misaki Mizumoto, Yoshiaki Kanemaru, Shinya Yamada +7
The Resolve instrument on the X-ray Imaging and Spectroscopy Mission (XRISM) uses a 36-pixel microcalorimeter designed to deliver high-resolution, non-dispersive X-ray spectroscopy…
The nature of spectral variability of the accreting pulsar Centaurus X-3 unveiled by NuSTAR observation covering two orbital cycles
Tsubasa Tamba, Hirokazu Odaka, Atsushi Tanimoto +3
We conducted a NuSTAR observation on the X-ray pulsar Centaurus X-3, which covered two consecutive orbital cycles of the source, including two eclipse durations. We…
Antihelium-3 Sensitivity for the GRAMS Experiment
J. Zeng, T. Aramaki, K. Aoyama +62
The Gamma-Ray and AntiMatter Survey (GRAMS) is a next-generation balloon/satellite mission utilizing a Liquid Argon Time Projection Chamber (LArTPC) detector to measure both MeV ga…
High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter: I. Ground test
Misaki Mizumoto, Tsubasa Tamba, Masahiro Tsujimoto +11
The spectroscopic performance of an X-ray microcalorimeter is compromised at high count rates. In this study, we utilize the Resolve X-ray microcalorimeter onboard the XRISM satell…
