A multi-tracer view on galaxies since cosmic noon: census, scaling relations and evolution

Main list: Physics and Astronomy Colloquia

Abstract

Dr Stijn Wuyts
University of Bath

Studies of the structural evolution of galaxies since the peak epoch of cosmic star formation 10 billion years ago have matured in recent years by combining the power of deep imaging lookback surveys and highly multiplexed integral-field spectroscopy.  With observations from the rest-frame ultraviolet to infrared we not only have a census of the stars within galaxies, but also probe their dust, ionised and molecular gas content.  Using diagnostics of gravitational and non-gravitational motions I will discuss the disk nature and mass budget of star-forming galaxies at cosmic noon, their turbulent interstellar medium, and the feedback processes responsible for large-scale galactic outflows.  I will contrast early star-forming galaxies to their quiescent counterparts at the same epoch, and will draw connections to their likely descendants at the present day.
