Low-Noise SiPM Light Readout and ASIC-Based Charge Readout of a Liquid Argon Time Projection Chamber for MeV Gamma-Ray Measurements
Satoshi Takashima, Hirokazu Odaka, Shota Arai +25
The authors built a compact liquid‑argon time projection chamber (NanoGRAMS) with low‑noise SiPM light readout and ASIC charge readout, and demonstrated its ability to detect and i…
X-ray Analysis and Photon-transport Simulations of SMC X-1: A Warped-disc Origin of the Superorbital Modulation
Satoshi Takashima, Hirokazu Odaka, Ryota Tomaru +3
The luminous accreting pulsar SMC X-1 is an appropriate target to explore the accretion dynamics. SMC X-1 shows unique quasi-periodic flux variability of 40-65days known as sup…
Development of Solar Flare X-ray Polarimeter with Micro-Pixel CMOS Sensors
Kouichi Hagino, Tatsuaki Kato, Toshiya Iwata +10
We are developing an X-ray polarimeter using micro-pixel CMOS sensors for solar flare X-ray polarimetry. The system consists of a 2.5-m pixel CMOS image sensor with a 12.8$\tim…
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…
