Research Division Seminar
Stellar populations of galaxies with Manga

Abstract

In this talk I will review my 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 gradients (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 the S0 population, pointing towards the existence of two distinct populations 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 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.
