Science with the Subaru Prime Focus Spectrograph: The Local Group
Rosemary Wyse, Professor, Physics and Astronomy, Johns Hopkins University,

The Subaru Prime Focus Spectrograph (PFS) will provide the unique capability of a wide-field (1.3 degree) massively multiplexed (2394 reconfigurable fibers) spectrograph on an 8-m telescope. The PFS team is developing a five-year, 360-night survey to be proposed as a Subaru Strategic Program, to address fundamental questions of cosmic evolution and the dark sector. We will investigate the formation and evolution of structure, from cosmological scales to the Local Group of galaxies. I will describe the motivation for the planned observations of faint stars in the Milky Way, in its satellite galaxies and in M31, and the insight we hope to gain into how galaxies form and evolve.
