Systematic effects on a Compton polarimeter at the focus of an X-ray mirror
M. Aoyagi, R. G. Bose, S. Chun +23
XL-Calibur is a balloon-borne Compton polarimeter for X-rays in the 15-80 keV range. Using an X-ray mirror with a 12 m focal length for collecting photons onto a beryllium sc…
GRBAlpha: the smallest astrophysical space observatory -- Part 1: Detector design, system description and satellite operations
András Pál, Masanori Ohno, László Mészáros +42
Aims. Since launched on 2021 March 22, the 1U-sized CubeSat GRBAlpha operates and collects scientific data on high-energy transients, making it the smallest astrophysical space obs…
Hitomi/XRISM micro-calorimeter
Kosuke Sato, Yuusuke Uchida, Kumi Ishikawa
We present an overview of the ASTRO-H (Hitomi) Soft X-Ray Spectrometer (SXS) and the X-Ray Imaging and Spectrometer Mission (XRISM) {\it Resolve} spectrometer. In each, a 36-pixel…
Early results from GRBAlpha and VZLUSAT-2
Jakub Ripa, Andras Pal, Masanori Ohno +37
We present the detector performance and early science results from GRBAlpha, a 1U CubeSat mission, which is a technological pathfinder to a future constellation of nanosatellites m…
Study of the Polarimetric Performance of a Si/CdTe Semiconductor Compton Camera for the Hitomi Satellite
Junichiro Katsuta, Ikumi Edahiro, Shin Watanabe +17
Gamma-ray polarization offers a unique probes into the geometry of the gamma-ray emission process in celestial objects. The Soft Gamma-ray Detector (SGD) onboard the X-ray observat…
