The prime focus spectrograph (PFS) on Subaru offers an unprecedented opportunity to explore the Galactic bulge. With its wide field, huge wavelength range, and large number of fibers, PFS is a potentially ideal instrument for this research. The Japanese astronomical community has made critical contributions in the bulge, and the Jasmine mission will probe the Galactic Center. The capabilities of PFS offer a unique opportunity for collaborations involving international partners to emerge.
The bulge is not part of the PFS core science program, so at present anyone in the Subaru community can propose programs in the bulge. Science topics could include large scale surveys of red giants including Miras, main sequence stars, horizontal branch and RR Lyrae stars, and unusual objects like X-ray sources and lenses. Exploration of the orbit structure as a function of age or metallicity could be interesting. At present, there are debates as to how much of the bulge/bar might be younger than 12 Gyr (globular cluster age) and what the role of ancient mergers played in the assembly of the bulge. In comparison to the 4MOST survey, the Subaru pfs has a near-IR component and is operating on an 8m telescope, and will have a pipeline that will provide abundances and radial velocities for giants.
Exploring the bulge poses unique challenges: The bulge is crowded and sky fiber positions may be hard to locate. Further, much of the bulge has Dec <-30 deg where calibration sources are not yet established. As PFS is a queue scheduled instrument, collaboration makes a great deal of sense and may benefit everyone. This meeting
is convened in order to explore the possibility of collaboration across communities, to work on research in the Galactic bulge. It is hoped that this meeting will bring opportunities for young researchers in Japan and elsewhere to work in this field.
