P-MaNGA: gradients in recent star formation histories as diagnostics for galaxy growth and death

We present an analysis of the data produced by the MaNGA prototype run (P-MaNGA), aiming to test how the radial gradients in recent star formation histories, as indicated by the 4000 ??break (Dn(4000)), H? absorption (EW(H?A)), and H? emission (EW(H?)) indices, can be useful for understanding disk g...
