We study radial profiles in H α equivalent width and specific star formation rate (sSFR)
derived from spatially resolved SDSS-IV MaNGA spectroscopy to gain insight on the
physical mechanisms that suppress star formation and determine a galaxy's location in the
SFR-M⋆ diagram. Even within the star-forming 'main sequence', the measured sSFR
decreases with stellar mass, in both an integrated and spatially resolved sense. Flat sSFR
radial profiles are observed for log (M⋆/M⊙)< 10.5, while star-forming galaxies of higher�…

We measure, a proxy for galaxy specific stellar angular momentum within one effective
radius, and the ellipticity, ε, for about 2300 galaxies of all morphological types observed with
integral field spectroscopy as part of the Mapping Nearby Galaxies at Apache Point
Observatory survey, the largest such sample to date. We use the diagram to separate early-
type galaxies into fast and slow rotators. We also visually classify each galaxy according to
its optical morphology and two-dimensional stellar velocity field. Comparing these�…

Abstract Mapping Nearby Galaxies at Apache Point Observatory provides the opportunity to
make precise spatially resolved measurements of the IMF slope in galaxies owing to its
unique combination of spatial resolution, wavelength coverage, and sample size. We derive
radial gradients in age, element abundances, and IMF slope analysing optical and near-
infrared absorption features from stacked spectra out to the half-light radius of 366 early-type
galaxies with masses 9.9–10.8 log M/M⊙. We find flat gradients in age and [α/Fe] ratio, as�…
