Transient Change of Io's Neutral Oxygen Cloud and Plasma Torus Observed by Hisaki

Ryoichi Koga Fuminori Tsuchiya Masato Kagitani Takeshi Sakanoi Kazuo Yoshioka Ichiro Yoshikawa Tomoki Kimura Go Murakami Atsushi Yamazaki H. Todd Smith Fran Bagenal

JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS 124(12) 10318-10331 2019年12月

Io's atmospheric oxygen atoms are heated by atmospheric sputtering and escape from Io's gravity, forming a neutral oxygen cloud around Io's orbit. This neutral cloud is important as a source of the Io oxygen plasma torus. Previous studies derived ...

The first astrophysical result of HISAKI: a search for the EUV He I lines a massive cool core cluster at z=0.7

Yuanyuan Su Tomoki Kimura Ralph Kraft Paul Nulsen Megan Gralla William Forman Go Murakami Atsushi Yamazaki Ichiro Yoshikawa

Astrophysical Journal 881(2) 2019年8月

Molecular cold gas and star formation have been observed at centers of
cool-core clusters, albeit at a level much smaller than expected from the
classic cooling model. Feedback from the supermassive black hole is likely to
have prevented hot gas f...
