Scientific results with the Subaru Telescope

The 8.2m Subaru Telescope had its astronomical first light at the Cassegrain focus in January 1999. The partial open use of the instruments started since December 2000. Currently, all the seven instruments are offered for open use and observational proposals are reviewed by the Time Allocation Committee of the Subaru Advisory Committee for each semester. The average competition rate is 6-7 times over the last four semesters. Up to the present, about 60 scientific papers have been published in refereed journals reporting scientific results based on observations of the Subaru Telescope. Described in this overview talk is a brief summary of some remarkable results mainly on extragalactic astronomy. The topics reported include near infrared galaxy number count, luminosity functions and clustering of Lyman break galaxies, high-z Lyman alpha emitting galaxy, population study of clusters of galaxies, gravitational lensing of clusters, properties of extremely red objects, studies on gravitational lensed quasar images and quasar absorption lines, a hypernova, metal poor stars, planet harboring stars, and issues on other specific objects. The preliminary progress reports on the Subaru Deep Field Survey and the supernovae survey are also given.
