Abstract: In this talk I will review recent work using the MaNGA dataset. MaNGA is an IFU survey which provides high spatial and spectral resolution of ~10,000 galaxies for its final data release (DR17). The IFU observations allow to derive spatially resolved stellar populations for galaxies up to ~1.5Re. I will show results on the stellar population (age, metallicity, alpha-elements) gradients of early-type galaxies (ETGs) divided into lenticular (S0), fast-rotating and slow rotating ellipticals (FR-E, SR-E) and their implications for the formation of massive galaxies. I will  discuss the impact of initial mass function gradients on the derivation of stellar mass and its effect on the values of mass/light effective radii. MaNGA observations have also been critical to identify a sample of ~20 hidden AGNs missed by integrated spectroscopic surveys (SDSS). Finally, I will show preliminary results on the identification of a relic galaxy candidate.
