Join us in welcoming Prof Power, ICRAR, for his talk on The CosmoDRAGoN Simulations – Modelling Realistic AGN Feedback in Realistic Cosmological Environments
AGN feedback – powerful outflows and jets from supermassive black holes in the cores of galaxies – is understood to be an important driver in the evolution of massive galaxies. However, the predictions of our best models for AGN feedback, based on sophisticated jet simulations, have been in tension with observations of jets in radio galaxy surveys. I will talk about our recent work on modelling the propagation of AGN jets in realistic cosmological environments – the CosmoDRAGoN Simulations (Yates-Jones et al. 2023, PASA, 40, 14) - and how this helps to alleviate the tension.
I'll also talk about our work to compare predictions from sophisticated but specialised astrophysical codes to model jets (PLUTO, an adaptive mesh refinement code that include special relativity and magnetohydrodynamics) and the more general codes we use in galaxy formation (including Arepo and SWIFT), and how we might better use such modelling to provide a direct calibration of black hole feedback models in galaxy formation simulations.
