PFS collaboration meeting

7 Jan 2025, 09:00 → 9 Jan 2025, 18:00 Asia/Tokyo

Overview: 

The Subaru Prime Focus Spectrograph (PFS) project squarely aims at addressing these long-standing questions. This innovative instrument  enables us to take spectroscopic observations of 2394 astronomical objects simultaneously on a large patch of sky several times larger than the size of the full moon. The lights from each star and/or galaxy observed are dispersed and recorded as spectra simultaneously covering a wide range of wavelengths from the near-ultraviolet, through the visible, and up to the near infrared regime (380 – 1260 nm).

 The PFS is now in the performance validation phase using commissioning observations at the Subaru Telescope site. The international collaborative team plans to start the major observing programme with 360 Subaru nights starting in March 2025.  In this face-to-face collaboration meeting, the team discuss the current status of intstruments, the strategy and plans of the first-year obseravtion, and then the science cases.  

Date: January 7-9, 2025
