Structure and Morphology of RESOLVE Galaxies in Relation to Environment, Gas, and Star Formation

We examine the structure and morphology of galaxies in the RESOLVE (REsolved Spectroscopy Of a Local VolumE) survey, a census of >1500 galaxies with baryonic mass >~10^9 Msun spanning multiple environments across >50,000 cubic Mpc of the nearby cosmic web. We investigate the statistical distribution of basic structural parameters as well as tidal streams and compact cores identified by image decomposition. Our results offer clues to the drivers of diversity in star formation and gas properties, particularly the unexpected phenomenon of red, gas depleted dwarf galaxies that are not satellites. RESOLVE was supported by NSF award AST-0955368.
