| Research Abstract |
We developed optical and near infrared small/intermediate telescopes to make a rapid imaging observations of gamma-ray burst afterglows, aiming at exploring the Universe at cosmic age of 0.2-1 billion years by using gamma-ray bursts as a probe. We also improved the instruments for Subaru telescope to achieve efficient follow-up observations of candidates of distant gamma-ray bursts. In 2009, we detected the gamma-ray burst afterglow exploded at cosmic age of 0.6 billion years. This broke the distance record, and proved the feasibility of this study. In addition, we studied related subjects such as gamma-ray burst host galaxies, nature of supernova explosions, and evolution of galaxies at the early Universe.
