Greeting

Dear XRISM users.

X-Ray Imaging and Spectroscopy Mission (XRISM) is the seventh Japanese X-ray observatory exploring the world of X-ray imaging and high-resolution spectroscopy, following ASTRO-H “Hitomi.” XRISM is an astrophysical satellite equipped with a long-waited X-ray micro-calorimeter and a conventional and reliable X-ray wide-field CCD camera on the focal plane of X-ray Mirrors. We believe the combination will bring the epoch-making and reliable results to you, XRISM users. The new vision of astrophysics you encounter may be too novel to cook only with the tools we prepare. We want to encourage the XRISM user community to develop new analysis tools or methods to explore the world of XRISM.

Enjoy the new space!

XRISMユーザーの皆様。

X線分光撮像衛星（XRISM）は、ASTRO-H「ひとみ」を引き継ぎ、X線超高分解能撮像分光で新しい宇宙を切り拓く、我が国７番目のX線天文衛星です。XRISMは、時代を画するX線マイクロカロリメータをはじめ、長年の実績をもとに開発され信頼性をそなえた広視野のCCDカメラも搭載した、多くの研究者・技術者の長年にわたる開発の精華です。皆様には、XRISMの能力を最大限に生かし、新しくかつ確実な観測成果を挙げていただけるものと信じております。しかしながら、新しい装置が見せる新しい宇宙は、あらかじめ開発者が用意した道具だけでは、味わい尽くせないかもしれません。新しいモデルや新しい解析方法が必要になることもあるでしょう。ぜひ、XRISMをとことん活用するとともに、皆様の議論・要望・貢献によってコミュニティを成長させていただければと、願っております。XRISMの見せる宇宙をお楽しみいただければ幸いです。

Tashiro, Makoto (XRISM PI)
