Exploring the Star Formation Histories of Galaxies in Different
  Environments from MaNGA Spectra
  The star formation history (SFH) of galaxies allow us to investigate when
galaxies formed their stars and assembled their mass. We can constrain the SFH
with high level of precision from galaxies with resolved stellar populations,
since we are able to discriminate between stars of different ages from the
spectrum they emit. However, the relative importance of secular evolution
(nature) over nurture is not yet clear, and separating the effects of
interaction-driven evolution in the observed galaxy properties is not trivial.
The aim of this study is to use MaNGA (Mapping Nearby Galaxies at APO) Integral
Field Unit (IFU) data, in combination with multi-wavelength data, to constrain
the SFH of nearby isolated galaxies. We present here the new techniques we are
developing to constrain the SFH with high level of precision from Spectral
Energy Distribution (SED) fitting. This study is part of a China-Chile
collaboration program where we are applying these new techniques to investigate
how galaxies formed and evolve in different environments.
