Wednesday 10 Mar 2021IFUs, nearby galaxies, and resolved stellar feedback

Anna McLeod -

Remote seminar 14:00-15:00

Over the past decade, integral field units (IFUs) have revolutionized our approach to resolved studies in nearby galaxies. Where we would typically be limited to observing proposals in which we ask for a few tens of slit positions to analyze e.g. abundance gradients, HII region kinematics, or properties of stars, we can now perform these analyses with orders-of-magnitude better efficiency for hundreds to thousands many more regions over entire nearby galaxies. In particular, the combination of IFU spectroscopy with high spatial resolution photometry is proving to be a game changer for stellar feedback studies, because it allows us to quantify feedback from the bottom up, i.e. from individual massive stars to their effect on galaxy scales. I will showcase some of the most recent results in this area, and share some preliminary yet exciting results from a VLT/MUSE data set of the nearby galaxy NGC 300.
