Abstract

We present the current status and future plan of the instruments at the Subaru Telescope. The Prime Focus Spectrograph (PFS) achieved the engineering first light in September, 2022. The installation of the PFS subsystems will be completed in November, 2023, and it is entering the final stage of the commissioning. For the next generation wide-field facility instrument ULTIMATE-Subaru, it successfully passed the preliminary design review and started the detailed design study for the GLAO system in 2022. There are ongoing projects for the facility AO system (AO188) including the upgrades of the deformable mirror and wavefront sensors. In addition, we are discussing implementations of the Nasmyth Beam Switcher, which enables remotely switching the instruments downstream of AO188, for more efficient operation at NsIR focus. As for the visitor instruments, there are a growing number of interests to carry in new instruments, upgrade existing ones, or resume operations of decommissioned instruments as visitor instruments. We are having discussions to better coordinate these demands and develop a future roadmap of NsIR instrumentation including both facility and visitor instruments.
