MOIRCS




The Update for S18A Applicants

2017-07-27

MOIRCS is in Regular Operation

    MOIRCS will be operated under the "regular" status during S18A 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


Current Status of the MOIRCS Upgrade Project

Posted 2017-07-22

There is a nice web-released article by Subaru about the story of the detector upgrade works.

Future Plan

We are planning to introduce the IFU spectroscopy function to MOIRCS, as well as the upgrade of the current MOS system. The system design and fabrication is on-going. But the date of the downtime is still TBD (late 2018?).

We will announce the plan here when it is fixed.



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.
