Kiyoto Yabe: Prime Focus Spectrograph of Subaru Telescope - commissioning status and scientific plan

Prime Focus Spectrograph (PFS) is the next-generation flagship instrument of Subaru Telescope on Maunakea in Hawaii. It has capability to conduct simultaneous multi-object spectroscopy from optical to NIR (380-1260 nm) with ~2400 fibers on the prime focus with ~1.3 deg2 field-of-view. PFS is an international collaboration project and the development of hardware and software has been made around the world. Most of hardware have been arrived and integrated at Subaru and now it is under its commissioning phase using night time. The unique and powerful capability of PFS will further strengthen Subaru's leading role in a various fields of cosmology and astronomy. Using PFS, in combination with data taken with a wide-field imager called Hyper Suprime-Cam (HSC) on Subaru, we are planning a large spectroscopic survey program over ~5 years to address various modern questions on cosmology, galaxy formation and evolution, and galactic archaeology. In this talk, we will present the current status of the project and what we do with this unique instrument.
