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…
Possible time-variable iron-K emission in the circumnuclear region of the Circinus galaxy
Aiko Miyamoto, Taiki Kawamuro, Hirokazu Odaka +2
We present imaging and spatially resolved spectral analyses of eight Chandra data taken for the Circinus galaxy in 22 years to reveal neutral iron-K emission on a cir…
Unraveling the structure of the stratified ultra-fast outflows in PDS 456 with XRISM
Yerong Xu, Luigi C. Gallo, Kouichi Hagino +18
Multiple clumpy wind components () in the luminous quasar PDS 456 have recently been resolved by XRISM in the Fe-K band for the first time. In this paper, we i…
XL-Calibur measurements of polarised hard X-ray emission from the Crab
Hisamitsu Awaki, Matthew G. Baring, Richard Bose +46
We report measurements of the linear polarisation degree (PD) and angle (PA) for hard X-ray emission from the Crab pulsar and wind nebula. Measurements were made with the XL-Calibu…
XL-Calibur Polarimetry of Cyg X-1 Further Constrains the Origin of its Hard-state X-ray Emission
Hisamitsu Awaki, Matthew G. Baring, Richard Bose +36
The balloon-borne hard X-ray polarimetry mission XL-Calibur observed the Black Hole X-ray Binary (BHXRB) Cygnus X-1 (Cyg X-1) during its nearly six-day Long Duration Balloon (LDB)…
Structured ionized winds shooting out from a quasar at relativistic speeds
XRISM collaboration
Evidence indicates that supermassive black holes exist at the centers of most galaxies. Their mass correlates with the galactic bulge mass, suggesting a co-evolution with their hos…
