Subaru FMOS now and future

摘要

Fiber Multi Object Spectrograph “FMOS” on Subaru Telescope is capable of configuring 400 fibers on the 30-arcmin diameter field of view at the prime focus for near-infrared (0.9–1.8 μm) spectroscopy, and this instrumenthas been open as a common-use instrument since May 2010. In this article, an overview of the instrument isgiven first, and then the typical operational sequence in science observation and a few notable features of theinstrument are explained. In (see manuscript) 5, the instrument performance in terms of fiber positioning, auto guiding, andsensitivity to emission lines are highlighted. Recently (since March 2012) a Subaru Strategic Program (SSP)has started with FMOS to conduct a wide-field galaxy survey for a cosmological experiment. Upgrading fiberconfiguration by using a “metrology camera” has also been under discussion, which will enable to measure thepositions of the 400 fibers quickly and shorten the fiber configuration time significantly. We will also report thestatus of these recent activities.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
