| Research Abstract |
Using the multi-object infrared camera and spectrograph (MOIRCS) on the 8.2 m Subaru Telescope atop of Mt. Mauna Kea in Hawaii, USA (operated by the National Astronomical Observatory of Japan), we have made infrared deep imaging surveys for a few sky areas. We have been also making similar infrared surveys using the VISTA telescope of European Southern Observatory and the Hubble Space Telescope. Through these observations, we have found that low-metallicity star formation occurred in very high redshift galaxies.
