Disentangling the complicated lives of lenticular galaxies Most galaxies consist of a dispersion-dominated bulge region and a regularly rotating disk. These components have built up their mass separately through different processes, yet are evolving together. It has become commonplace to separate the light from bulge and disk regions to better understand their formation and contribution to their host galaxy.
The advent of large-scale multi-object integral field spectroscopic surveys such as Mapping Nearby Galaxies at APO (MaNGA) have provided spatial spectroscopic coverage of thousands of galaxies. MaNGA’s goal is to understand the “life history” of present day galaxies from imprinted clues of their birth and assembly, through their ongoing growth via star formation and merging, to their death from quenching at late times. I will detail some of the latest results from the MaNGA galaxy survey, including efforts to study stellar populations in lenticular galaxies within bulge and disk regions, and an investigation into the influence of bars on the secular evolution of disk galaxies.
