The Case for AGN Feedback Philip Hopkins Paul Torrey, Xiangcheng Ma, Daniel Angles-Alcazar Large scales: Gravity + CDM Works! Observations vs Theory (SDSS vs Millennium Simulation) Large scales: Gravity + CDM Works! Observations vs Theory (SDSS vs Millennium Simulation) What’s missing? We have to simulate it! LMC 
 
 - EVERYTHING on scales 
 ~ 10-9 - 1027 cm is terribly messy, 
 … but we are doing it! The FIRE Project: • SNe (II & Ia) • Stellar Winds (O & AGB) • Photoionization (HII) & Photo-electric • Radiation Pressure (IR & UV) • Cosmic Rays
 • all with… • Magnetic fields • Cooling, chemistry • Conduction, viscosity, etc. Yellow: hot (>106 K) Pink: warm (ionized, ~104K) Blue: cold (neutral <104 K) The FIRE Project: (movies at fire.northwestern.edu) 10 kpc Stars (Hubble image): Gas: Magenta: cold Green: warm (ionized) Blue: Young star clusters Red: hot Red: Dust extinction Andrew The FIRE Project: Latte Wetzel (arXiv:1602.05957) Andrew The FIRE Project: Latte Wetzel (arXiv:1602.05957) Andrew The FIRE Project: Latte Wetzel (arXiv:1602.05957) Andrew The FIRE Project: Latte Wetzel (arXiv:1602.05957)
