This page is an explanation of the quick reduction ofSubaru HDS (High Dispersion Spectrograph) data on sumda system at Subaru summit/remote observation system. Basically, this page describes the quick ...

InfraRed Doppler (IRD), which experienced the first light in 2018, is an infrared instrument used in the search for exoplanets (extrasolar planets). IRD is specialized for finding exoplanets with the ...

Like, far FAR out, man! Astronomers using the Subaru Telescope have discovered a planetoid that is almost 4 times farther from the Sun than Pluto, making it the most distant object ever observed in ...

The Subaru Telescope has spotted the terminal ends of dark matter filaments in the Coma Cluster stretching across millions of light years. This is the first time that strands of the cosmic web ...

Linear polarimetry with IRCS and AO188 is available in two settings (near-infrared [NIR] 0.95−2.5μm and thermal-infrared [TIR] 1.92−4.80μm), which are offered on a shared-risk basis. Users who want to ...

The Subaru Telescope has started a new outreach camera project in collaboration with the Asahi-Shimbun, one of the most popular newspapers in Japan. This camera is used for live streaming of the night ...

The first exoplanet discovered by the Subaru Strategic Program using the infrared spectrograph IRD on the Subaru Telescope (IRD-SSP) has been announced. This planet, Ross 508 b, is a super-Earth with ...

国立天文台、東京大学などの研究チームは、すばる望遠鏡搭載の超広視野主焦点カメラ Hyper Suprime-Cam を用いた大規模探査観測データから、重力レンズ効果の解析に基づく史上最高の広さと解像度を持つダークマターの「地図」を作成しました (図1、動画)。

Performance of AO is characterized by a Strehl ratio (a peak intensity normalized by that of PSF without any turbulence) and FWHM of the PSF. These depend on a the AO guide star magnitude, seeing, sky ...
