Kartik Sheth (NRAO) ---- The Evolution of Stellar Structure in Galaxies as Seen by S4G

I will describe the latest results from the Spitzer Survey of Stellar Structure of Galaxies (S4G) focusing specifically on the new result that the bar fraction as a function of galaxy mass is consistent with previous cosmological results from the COSMOS survey, but at odds with other local studies. I will also discuss the structure of bars in this context and provide an update on the role of bars in feeding black holes and initiating star formation activity in disks. I will also update the audience on the new Cycle 10 Spitzer survey called "ETGs: Not Dead Yet!"
