GBT EDGE: A Representative Survey of the z=0 Universe with Full IFU Spectroscopy

Abstract

Spatially-resolved surveys of galaxies in both the optical and mm-wave bands are crucial to connect local physics to observed global trends and to anchor physical understanding of the processes that shape galaxies. What is sorely needed is such a survey for a galaxy sample that is representative of the local population, with depth capable of producing statistically meaningful results, and at a resolution that can be directly compared to cosmological simulations. We propose Argus OTF CO 1-0 observations of 150 galaxies selected from the CALIFA IFU sample to, jointly with the 126 galaxies observed with CARMA, produce a statistically meaningful dataset with negligible cosmic variance which will inform galaxy evolution science in the coming years. CALIFA provides the best z=0 IFU sample for resolved molecular gas studies: its galaxies are nearer and better resolved than those in MaNGA or SAMI, it is representative of the population for log(M*/Msun)=9-11.5, and it provides excellent data for all key optical transitions. With these observations we will answer fundamental questions regarding galaxy growth and quenching, star formation regulation, and the structure of the molecular component, and produce a lasting legacy dataset for the z=0 universe.
