    Institution: University of Nevada-Las Vegas Title: Multiphase Supersonic Outflows in Active Galactic Nuclei Abstract: Large-scale mass outflows from Active Galactic Nuclei (AGN) naturally connect  a galaxy to its central black hole and enable an AGN feedback mechanism. However, quantifying the feedback efficiency is challenging because it involves considering  multidimensional fluid dynamics, radiative processes, magnetic processes, …
