Modeling the Multi-messenger Signatures of Supermassive Black Hole Evolution
Laura Blecha (University of Florida)

Although BHs are key components in the evolution of galaxies, many details of how they form, grow, and interact with their hosts remain uncertain. Future X-ray missions such as XRISM, Athena, AXIS, and Lynx would provide unprecedented probes of obscured galactic nuclei, BH fueling and feedback processes, and early BH growth, especially when combined with multi-wavelength and multi-messenger observations. I will discuss how numerical simulations constitute another “messenger” that is essential to fully realizing these goals. Specifically, I will describe our recent results regarding the role of galaxy mergers in active galactic nucleus (AGN) fueling and feedback, as well as predicted electromagnetic signatures of (dual, obscured) AGN and BH binary inspiral, merger, and recoil. Our work employs hydrodynamics simulations and radiative transfer calculations from galactic to cosmological scales. Finally, I will briefly outline ongoing efforts to create new sub-grid models of BH seed formation, fueling, and feedback that will enable detailed predictions for future X-ray spectroscopic and imaging surveys, in addition to gravitational-wave source predictions.
