SDSS-IV MaNGA: star formation cessation in low-redshift galaxies I: dependence on stellar mass and structural properties

We investigate radial gradients in the recent star formation history (SFH) of 1917 MaNGA galaxies with 0.01 < z < 0.14. For each galaxy, we obtain two-dimensional maps and radial profiles for three spectroscopically-measured parameters that are sensitive to the recent SFH: Dn(4000) (the 4000̊A...
