NOTICE: Hibernation of MOIRCS from S21A for 2 Years

    Subaru Telescope has decided to accept the science operation of SWIMS as a PI-type instrument from S21A for two years. In exchange, we will hibernate MOIRCS during the period due to our operational, technical and budgetary reasons. We are sorry for any inconvenience.

Unavailability of the VPH-Y/J/H Grisms

    We removed the VPH-Y grism in early 2020 due to the low frequency of the use. And also, we will remove the VPH-J and the VPH-H grisms during the hibernation period, because of the availability of the new (and better) LS_J and LS_H grisms. If you need these grisms for your science after hibernation (i.e. from S23A), please request the SA to reinstall (at least half year before the reopening).




Introduction

MOIRCS (Multi-Object InfraRed Camera and Spectrograph) provides wide-field imaging and long-slit/multi-object (MOS) spectroscopic capabilities in the 0.9 ~ 2.5 µm spectral range under the natural seeing condition. The 4'×7' field of view is covered by two 2048×2048 infrared detector arrays with the spatial resolution of 0.116 arcsec/pixel. The detector has been updated to the Hawaii2 RG in late 2015.

For the imaging mode, the standard MKO YJHKs filters as well as some narrow-band filters are available. See the Imaging Mode Page for more details.

The MOS performance of MOIRCS spectroscopy mode is the most notable feature of the instrument. Using the cooled aluminum slit masks, MOIRCS can acquire 40 ~ 60 object spectra simultaneously across 0.9~2.5 micron wavelength range. The low-resolution (R~500) and high-resolution (R~3000) grisms are available. See the Spectroscopy Page for more details. All MOS observers/applicants should carefully read the MOS observation pages.
