Title : WHAT MAKES THE FAMILY OF BARRED GALAXIES SO RICH?
Abstract: Galaxy evolution is governed by mergers and cold accretion from cosmological filaments. But disk galaxies are embedded in dark matter halos and a large fraction of them host stellar bars. But is the disk aware of the dark matter beyond its gravitational pull? How do galactic disks "talk" to the dark matter and what is the role of bars in this process? Can this interaction be a sign of an internal evolution in galaxies? For example, can it shape the Hubble Fork Diagram? In my talk I will present our latest results on the effect dark matter has on the disk evolution and will discuss the reverse effect of the disk on the dark matter halo.
