MOIRCS




The Update for S19B Applicants

2019-02-01

MOIRCS is in Regular Operation

    MOIRCS will be operated under the "regular" status during S19B Semester.

    Please carefully read the following MOIRCS webpages before you design your observing strategy. If you have any question, please contact the primary support astronmer (see the bottom of the page).

For MOS Applicants

Notes for Future Operation

  • MOIRCS may hibernate for 1 to 2 years in the near future, if Subaru allows SWIMS to carry out the science operation in Subaru. The discussion on the SWIMS science operation will start soon. We will announce here if the situation become clear.

  • We are planning to replace the current VPH-J and VPH-H grisms to the new high efficiecny, wide-spectral coverage grisms in 2020 (VPHJ) to 2021 (VPHH). These VPH grism will be unavailable by S20A.



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 (the R1300 medium-resolution grism is also available but have some issues). See the Spectroscopy Page for more details. All MOS observers/applicants should carefully read the MOS observation pages.
