MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is an ongoing project as part of the Fourth Sloan Digital Sky Survey (SDSS-IV). The survey uses Integral Field Spectroscopy to measure spatially resolved spectra of 10,000 galaxies in the local universe. We use the Fifth MaNGA Product Launch (MPL-5) to measure spatially resolved star formation rates of ~1400 star forming galaxies. We begin with a simple model based on a galaxies Ha emission to estimate the star formation rate and then use an internally calibrated measure based on D4000 to detect star formation within galaxy regions contaminated by AGN/LI(N)ER emission. We study the radial distribution of specific star formation and it's dependence on various galaxy properties, such as stellar mass and whether the galaxy is a Central or Satellite.
