Introduction

---

The Subaru Prime Focus Spectrograph (PFS) is a spectrograph system mounted at the prime focus of the Subaru telescope. Four identical spectrograph modules are fed by a total of ~2400 fibres, allowing for simultaneous observations of ~2400 targets within a very wide-field (~1.25 deg²). The spectra cover a wide wavelength range from 0.38 μm to 1.26 μm, with a resolving power of approximately 2,300 in the blue channel, and up to 5,000 in the red channel (medium resolution mode).

In principle, observations will be conducted in queue mode, to maximize the observing efficiency by optimizing the fiber positions. Classical mode observations can be requested for observations that require exposure times other than 15 min, specific configuration of pointing centers, or time-critical execution.

Please review the Observations page carefully when planning to observe with PFS. For proposal preparation, please also refer to Getting Started Manual.
