Steel frame of the enclosure was completed and its rotation test succeeded |
|
Optical infrared telescopes such as TAO are installed in buildings with large openings in order to avoid the effects of rain and wind. Many buildings used to be spherical, called etelescope domesf, but now many buildings are cylindrical or similar in shape, called etelescope enclosuref generally...

SWIMS open use observations at the Subaru Telescope completed |
|
The Simultaneous-color Wide-field Infrared Multi-object Spectrograph (SWIMS), the first-generation instrument for the TAO 6.5-m telescope, has completed its open use operation at the Subaru Telescope (NAOJ, in Hawaii), which had lasted 2 years since 2021. We began designing and manufacturing SWIMS in 2009, conducted ...

Engineering observation of SWIMS-IFU (Integral field unit for SWIMS, Simultaneous-color Wide-field Infrared Multi-object Spectrograph) on the Subaru Telescope succeeded |
|
Spectroscopic observation is necessary to probe the detailed physical state of stars, galaxies, and other astronomical objects. In spectroscopic observation, dispersing the light from astronomical objects into different wavelengths and measuring the intensity of light at each wavelength allows for detecting various characteristics of the light coming from astronomical objects to determine their temperature, density, elemental abundance, and ...
