Structural Evolution of the Milky Way-like galaxies over the last 11 Gyrs

Ana S. Paulino Afonso

With the advent of NIR IFU spectroscopy it has become possible, for the first time, to observe resolved spectral properties of galaxies. We are able to investigate spatial distribution of star formation rates, metallicities, AGN activity and stellar masses derived from the optical rest-frame up to z~3. These properties can be directly compared to those obtained in the local universe. My doctoral thesis project aims to compare the evolution of galaxies from the peak of star formation history of the universe until the present day. Such study can only be possible with the analysis of star-forming galaxies in three important aspects: galaxy morphology, galaxy kinematics, and resolved spectroscopic analysis. The first allows us to classify galaxies into different populations and then set up the comparisons of similar structures. The second makes possible the derivation of the rotation curves and dynamical masses. The third permits us to link the star formation process to the dynamics, morphology and metallicities. To pinpoint the anatomy of Hα-selected galaxies, I have conducted a morphological analysis which I will present in this seminar.
