Title: STELLAR STRUCTURES AS TRACERS OF GALAXY EVOLUTION


Abstract: Disk galaxies are complex systems shaped by different stellar structures such as bulges, disks, and bars. Every galaxy structure keeps a unique memory of their past evolution, thus, understanding the formation path of disk galaxies can only be achieved by analysing separately all these independent footprints of past evolution. In this talk, I will broadly review specific cases where stellar structures are fundamental to understand galaxy evolution and I will describe our current efforts along this research line. In particular, I will introduce C2D, a new algorithm able to separate the spectra of the different galaxy structural components such as bulge, disc, and bar using the information provided by integral field spectrographs (IFS). The combination of C2D with full spectrum fitting techniques is providing us with a new picture of the galaxy mass assembly throughout cosmic time. The development and application of these techniques to future IFS instruments at the ELT and JWST is necessary to maximise their scientific exploitation.
