Subaru Users Meeting 2026
June 17 - 19, 2026 JST
Large Seminar Room, Mitaka Campus, National Astronomical Observatory of Japan (NAOJ)
Purpose
The Subaru Telescope is entering a new phase of scientific activity. With the ʻŌnohiʻula Prime Focus Spectrograph (PFS) now in science operation, high-quality data are being delivered, enabling exciting scientific results across a range of astronomical fields.
To enhance the scientific impact of Subaru, it is essential to advance the development of ULTIMATE-Subaru, strengthen synergies with LSST and Roman, and continue innovation through instrument development. In parallel, fostering the next generation of researchers who will lead future Subaru science and instrumentation is an important priority.
The annual Subaru Users Meeting provides a vital forum for users to gather, share scientific results, understand future prospects, and explore opportunities for collaboration. This year, the meeting includes a dedicated session for students and early-career researchers to promote active participation and interaction.
We encourage all members of the Subaru community to participate in this Users Meeting and to contribute to constructive discussions that will help shape the future of the Subaru Telescope, including its long-term vision, “Subaru 3.”
