High-multiplex and deep spectroscopic follow-up of upcoming panoramicdeep-imaging surveys like LSST, Euclid, and WFIRST is a widely recognized andincreasingly urgent necessity. No current or planned facility at a U.S.observatory meets the sensitivity, multiplex, and rapid-response time needed toexploit these future datasets. FOBOS, the Fiber-Optic Broadband OpticalSpectrograph, is a near-term fiber-based facility that addresses thesespectroscopic needs by optimizing depth over area and exploiting the apertureadvantage of the existing 10m Keck II Telescope. The result is an instrumentwith a uniquely blue-sensitive wavelength range (0.31-1.0 um) at R~3500,high-multiplex (1800 fibers), and a factor 1.7 greater survey speed andorder-of-magnitude greater sampling density than Subaru's Prime FocusSpectrograph (PFS). In the era of panoramic deep imaging, FOBOS will excel atbuilding the deep, spectroscopic reference data sets needed to interpret vastimaging data. At the same time, its flexible focal plane, including a mode with25 deployable integral-field units (IFUs) across a 20 arcmin diameter field,enables an expansive range of scientific investigations. Its key programmaticareas include (1) nested stellar-parameter training sets that enable studies ofthe Milky Way and M31 halo sub-structure, as well as local group dwarfgalaxies, (2) a comprehensive picture of galaxy formation thanks to detailedmapping of the baryonic environment at z~2 and statistical linking of evolvingpopulations to the present day, and (3) dramatic enhancements in cosmologicalconstraints via precise photometric redshifts and determined redshiftdistributions. In combination with Keck I instrumentation, FOBOS also providesinstant access to medium-resolution spectroscopy for transient sources withfull coverage from the UV to the K-band.
