"Transforming Spirals into S0s"

There is now little doubt that Lenticular (S0) galaxies are the descendants of spiral galaxies whose star-formation ceased. In this talk I will present some of the evidence we have gathered in support of this hypothesis and the physical mechanisms driving the transformation. I will also discuss some recent and ongoing work on applying spectroscopic bulge-disk decomposition techniques to multiple IFU surveys such as MaNGA.
