Stellar feedback: from stars to galaxies

Dr Anna McLeod , Centre for Extragalactic Astronomy, Durham University, UK

Feedback from massive stars plays a central role in shaping the evolution of galaxies. Conversely, different galactic environments play a central role in regulating the impact of massive stars. Yet, despite a solid qualitative understanding of feedback, our quantitative knowledge about the interdependence of feedback and environment remains poor. Until recently, only a small number of star-forming regions had adequate observational information on both gas and stars needed for detailed stellar feedback studies. Over the past decade, integral field units (IFUs) have revolutionized our approach to resolved stellar feedback studies in nearby galaxies. In this talk I will present recent results of IFU nearby galaxy surveys, showcasing how these can be used to simultaneously characterize the feedback-driven interstellar medium and individual feedback-driving stars up to Mpc distances, and I will discuss how this enables the first empirical quantification of the interdependence between stellar feedback and the environments massive stars form in. Lastly, if there is time, I will also be talking about how IFU data can lead to truly serendipitous discoveries. Dr. McLeod will be based at the Astronomisches Rechen-Institut for her visit to Heidelberg and will be available for meetings by arrangement with her host, Melanie Chevance (chevance@uni-heidelberg.de). Those unable to attend the colloquium in person are invited to participate online through Zoom (Meeting ID: 942 0262 2849, passcode 792771) using the link: https://zoom.us/j/94202622849pwd=dGlPQXBiUytzY1M2UE5oUDRhbzNOZz09
