Research Abstract |
We have developed a next-generation near-infrared high-resolution spectrograph "WINERED", which enables high-sensitive absorption spectroscopy of intergalactic medium in the re-ionization era. WINERED achieves a high-resolution of R=30, 000 despite its compact design and a high throughput that doubles that for conventional high-resolution spectrographs by narrowing the wavelength coverage(0. 9-1. 4um) and by using non-cryogenic optics. After completing the assembly and laboratory experiments, we started astronomical observations with the 1. 3m telescope of Koyama Astronomical Observatory at Kyoto Sangyo University. We also experimentally constructed an observational scheme for the follow-up of gamma-ray bursts.
