Development of Next-generation Infrared High-resolution Spectrograph for Studying the Cosmic Re-ionization Era with High Redshift Gamma-ray Bursts

我们开发了下一代近红外高分辨率光谱仪“WINERED”，它可以在再电离时代对星系间介质进行高灵敏度的吸收光谱分析。WINERED实现了R= 30,000的高分辨率，尽管其紧凑的设计和高通量，是传统高分辨率光谱仪的两倍，通过缩小波长覆盖范围(0。1胜9负。4um)和使用非低温光学。在完成组装和实验室实验后，我们开始用1号卫星进行天文观测。京都工业大学小山天文台的3米望远镜。我们还通过实验构建了一个伽马射线暴后续观测方案。

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.
