Structural Evolution of Galaxies since Cosmic Noon
Title: Structural Evolution of Galaxies since Cosmic Noon
Speaker: Professor Stijn Wuyts (University of Bath, UK)

Abstract: In this talk he will discuss the geometry structure and morphological transformation of star-forming and quiescent galaxies from the peak of cosmic star formation to the present day. Resolved observations from multiple wavelengths and tracers enable us to reconstruct where stars form within galaxies and how stellar distributions are assembled, while simultaneously revealing insights into the evolving 3D spatial distributions of stars and dust. Integral-field spectroscopy adds to this the kinematic perspective, probing both gravitational and non-gravitational motions, and with its signatures of dark matter content and feedback in action. He will draw from HST, JWST, ALMA and IFU observations to illustrate the structural make-up of galaxies across cosmic time, and will draw connections to state-of-the-art cosmological simulations.
