Cosmology Seminar- Simulating the Impact of AGN Feedback on X-ray and tSZ Observations

Active Galactic Nuclei (AGN) feedback plays an important role in galaxy formation, impacting star formation and gas conditions across a range of physical and temporal scales. Without AGN feedback, modern cosmological simulations fail to replicate global galaxy properties. However, each simulation employs a unique prescription that can vary dramatically in its treatment of the underlying physical mechanisms. One promising means of better constraining these AGN feedback models is through the circumgalactic medium, as CGM gas should be impacted in differing ways based on the implementation of feedback in each simulation. In this talk, I will explore how the AGN feedback prescriptions in the SIMBA and EAGLE simulations shape the CGM. I will assess the observability of these differences by generating mock thermal Sunyaev-Zel'dovich and X-ray observations and comparing against stacked CGM observations from the Atacama Cosmology Telescope and the eROSITA-SRG instrument. I will also present work modifying the AGN treatment in the SIMBA simulation, directly probing the impact different modes of feedback can have on AGN host galaxies and the CGM. These results will help determine how current and upcoming missions can be used to constrain models of AGN feedback in cosmological simulations.
