Hitomi-HXT deconvolution imaging of the Crab Nebula dazzled by the Crab pulsar
Mikio Morii, Yoshitomo Maeda, Hisamitsu Awaki +3
We develop a new deconvolution method to improve the angular resolution of the Crab Nebula image taken by the Hitomi HXT. Here, we extend the Richardson-Lucy method by introducing…
Multi-Image X-ray Interferometer Module: I. design concept and proof-of-concept experiments with fine-pitch slits
Kazunori Asakura, Kiyoshi Hayashida, Tomoki Kawabata +7
We propose a novel x-ray imaging system, Multi-Image X-ray Interferometer Module (MIXIM), with which a very high angular resolution can be achieved even with a small system size. M…
A broadband X-ray imaging spectroscopy in the 2030s: the FORCE mission
Koji Mori, Takeshi G. Tsuru, Kazuhiro Nakazawa +49
In this multi-messenger astronomy era, all the observational probes are improving their sensitivities and overall performance. The Focusing on Relativistic universe and Cosmic Evol…
Ground test results of the micro-vibration interference for the x-ray microcalorimeter onboard XRISM
Takashi Hasebe, Ryuta Imamura, Masahiro Tsujimoto +8
Resolve is a payload hosting an X-ray microcalorimeter detector operated at 50 mK in the X-Ray Imaging and Spectroscopy Mission (XRISM). It is currently under development as part o…
Mechanical cryocooler noise observed in the ground testing of the Resolve X-ray microcalorimeter onboard XRISM
R. Imamura, H. Awaki, M. Tsujimoto +5
Low-temperature detectors often use mechanical coolers as part of the cooling chain in order to reach sub-Kelvin operating temperatures. The microphonics noise caused by the mechan…
Solar abundance ratios of the iron-peak elements in the Perseus Cluster
Hitomi Collaboration
The metal abundance of the hot plasma that permeates galaxy clusters represents the accumulation of heavy elements produced by billions of supernovae. Therefore, X-ray spectroscopy…
