H. McNaught and Y. Ikari at Moriyama. Katsuji Koyama (b. 1945), a professor emeritus of Kyoto University, works in x-ray astronomy and cosmic ray physics. In particular, he has investigated the x-ray emission mechanisms and structures of supernova remnants. He was a vice-president of the Astronomical Society of Japan during 1999-2000.
