As always, the seminar will be in C4 on Wednesday at 15:45. If you would like to join for lunch (~13:00 on Wednesday, likely at Lakeside Arts), please let me (Jesse) know by tomorrow afternoon. As usual, we can sponsor a few postgraduates to join. The schedule
is listed below:</div>

How massive galaxies quench in the Simba simulations<br>
<br>
Cosmological simulations of galaxy formation have matured rapidly in the last few years, with recent models combining structure formation, hydrodynamics, stellar and black hole growth, and associated feedback processes to accurately reproduce key demographical
properties observed in the galaxy population. Our group's Simba simulation suite includes unique input physics that have dramatic implications particularly for the growth and quenching of massive galaxies. I will show how Simba's AGN jet feedback impacts
the surrounding circum-galactic and intergalactic medium on surprisingly large scales. Using the Hyenas zoom simulations based on Simba, I will further show how Simba's jets blow X-ray cavities as observed, depositing energy and evacuating halo gas, the first
time this has been demonstrated within a full hierarchical galaxy formation context. Such feedback also goes helps explain some puzzling trends seen in the stellar-to-halo mass relation and the matter power spectrum.</div>
