The growth of disks and bulges

Deep integral-field spectroscopy, coupled with high-resolution imaging from the optical to the far-infrared, allows us to trace the growth of disk galaxies since the peak epoch of cosmic star formation, and the emergence of bulges within them as they reach the massive end of the mass function and eventually transition to quiescence.  I will present recent findings on the structural evolution of galaxies from deep lookback surveys with HST and ALMA, and insights on their kinematic nature leveraging the large multiplexing capabilities of modern-day spectrographs such as KMOS.

Speaker Introduction: 

Dr Stijn Wuyts is a Senior Lecturer in extragalactic astronomy at the University of Bath.  He obtained his PhD from Leiden University on the topic of "Red galaxies at High Redshift", worked on the interface between galaxy observations and simulations as W. M. Keck Fellow at the Harvard-Smithsonian Center for  Astrophysics, and further explored the distant universe as Junior Scientist at the Max Planck Institute for Extraterrestrial Physics.  At the University of Bath, he combines tracers of stars, dust, ionised and cold gas to reveal the physics governing the build-up of stars within galaxies near and far, and the evolution of their structure through cosmic time.
