Hayakawa Sachio

Hayakawa Sachio ( Japanese 早川 幸 男 , also Hayakawa Satio after the Kunrei transcription ; * October 16, 1923 , † February 5, 1992 ) was a Japanese astrophysicist, nuclear physicist, plasma physicist and particle physicist.

Life

Hayakawa studied at the University of Tokyo and was a student of Shin'ichirō Tomonaga and initially dealt with the theory of cosmic radiation. He belonged to a group of theoretical elementary particle physicists at Osaka Municipal University (as well as Yōichirō Nambu ) in the 1950s and also worked with Hideki Yukawa and Shoichi Sakata . In 1952 he received a full professorship at the newly founded Institute for Fundamental Physics in Kyoto. In 1958 he moved to Nagoya University , whose president he later became.

Hayakawa worked both theoretically and experimentally. He played a major role in the establishment of the KEK particle accelerator center . In plasma physics, he co-founded the Center for Plasma Physics at Nagoya University.

Independently of Philip Morrison , he proposed gamma-ray astronomy in the 1950s, and he studied nuclear reactions in stars. He later worked in infrared and X-ray astronomy (in which he had a leading role in Japan and initiated X-ray satellite programs) and most recently with research programs on gravitational wave detectors.

In 1989 he received the Marcel Grossmann Award .

He campaigned for international cooperation and was chairman of the IUPAC commission on astrophysics.
