(host: Niv Drory) (Tinsley Scholar: Exgal Group) "MaNGA: Mapping Nearby Galaxies at Apache Point Observatory - an IFU Survey of 10,000 Galaxies"
I will discuss the design, ongoing construction, and soon-to-begin execution of a new survey to obtain resolved spectroscopy for 10,000 nearby galaxies called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory). MaNGA is one of three programs that make up the 6-year SDSS-IV project, beginning in August 2014. MaNGA will deploy 17 fiber-bundle IFUs across the Sloan 2.5m Telescope's 3 degree field-of-view, targeting a mass-selected sample with a median redshift of 0.03, typical spatial resolution of 1-2 kpc, and a per-fiber signal-to-noise ratio of 5-10 in the outskirts of target galaxies. For each galaxy in the sample, MaNGA will provide maps and measured gradients of the age and chemistry of stellar populations, the gas-phase metallicity and star formation rates, as well as the velocity fields of both stars and gas. This unprecedented, rich data set will shed new light on the early formation history, ongoing growth, and eventual "death" via star-formation quenching of nearby galaxies.
