EA: MaNGA/SDSS-IV: Archaeological reconstruction of the radial and global growth of galaxies – Ávila-Reese

April 21 @ 11:15 am 12:00 pm CMT

The MaNGA survey has observed >10,000 local galaxies from SDSS using the integral field spectroscopy technique. By applying inverse stellar population synthesis (fossil record method) to their spatially resolved spectra, the local and global star formation (SF), chemical enrichment, and stellar mass growth histories of these galaxies were inferred. In this keynote talk, after briefly reviewing the survey and the publicly available products, I will present some selected results related to the archaeological inferences. The main questions we seek to answer are: How has the radial and global evolution of galaxies of different types been as a function of their mass and morphology? What has been their contribution, after correcting for volume completeness, to the cosmic SF history? When and how did the SF quenching process occur in elliptical galaxies?
