SUMMARY:Stellar populations of galaxies with Manga
DESCRIPTION:Stellar populations of galaxies with Manga\nDr. Helena Domingue
 z-Sanchez\n\nIn this talk I will review my recent work using the MaNGA dat
 aset. MaNGA is an IFU survey which provides high spatial and spectral reso
 lution of ~10,000 galaxies for its final data release (DR17). The IFU obse
 rvations allow to derive spatially resolved stellar populations for galaxi
 es up to ~1.5Re. I will show results on the stellar population gradients&n
 bsp;(age, metallicity, alpha-elements) 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 also show results from the PCA analysis of the MaNGA spectra of th
 e S0 population, pointing towards the existence of two distinct population
 s following different evolutionary tracks. I will  discuss the impact
  of initial mass function gradients on the estimations of stellar mass and
  their effect on the values of mass/light effective radii. MaNGA observati
 ons have also been critical to identify a sample of ~20 hidden AGNs missed
  by integrated spectroscopic surveys (SDSS). Finally, I will show prelimin
 ary results on the identification of a relic galaxy candidate.\n \nZo
