International Symposium

International Symposium On Gamma-ray Astrophysics 2002


"The Universe viewed in gamma-rays ---The University of Tokyo Workshop 2002---" will be held on September 25-28, 2002 in Kashiwa, Chiba, Japan. The purpose of this symposium is to discuss the new views of the universe grasped mainly in the rapidly developing high energy gamma-ray astrophysics in the energy range above 10 GeV. New ground-based observatories of very high energy gamma-rays are being built, energy threshold are being lowered, and stereoscopic observations with new telescopes will be started soon. The symposium will cover observational and theoretical aspects of Galactic and extragalactic sources of gamma-rays which contribute to the existence of nonthermal particles in the universe. Information of the photons in other energy regime is mandatory to uncover the secret of very high energy phenomena in the universe and multiwavelength campaigns will be also. This symposium is hosted by ICRR, University of Tokyo and sponsored by the Ministry of Education, Culture, Sports, Science and Technology of Japan and supported by High Energy AstroPhysics Association in Japan (HEAPA).


The official language of the Symposium is English. For oral presentation you can use an overhead projector or an LCD projector with XGA (1024x768) resolution. For poster presentation, the panel size is 100cm (w) x 180cm (h). LOC will supply pins for posting your poster paper.

Manuscripts for proceedings are available in PDF format.

[New!] Hard copies of proceedings are available from Universal Academy Press

Calender of Events


The venue of the symposium will be the main hall of "
Sawayaka Chiba Kenmin Plaza" near the Institute for Cosmic Ray Research (ICRR) of the University Tokyo, in Kashiwa, Chiba, Japan, which locates in Kashiwa campus, the newest major campus of University of Tokyo. An overhead projector and an LCD projector with a CCD camera and an RGB interface (XGA resolution) will be equipped for presentation.

Kashiwa City is located 30 kilometers northeast of Tokyo. The access map to our institute is here. The "Sawayaka Chiba Kenmin Plaza" is 5-min walk from ICRR.
