ASD Colloquium (Hybrid)
Multiphase Supersonic Outflows in Active Galactic Nuclei
Daniel Proga (UNLV)

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, and other factors. In this talk, I will summarize the main results from our ongoing work on developing a comprehensive physical model of AGN outflows. Observations indicate that these outflows are not smooth, including the fastest ones, like the ultrafast outflows. Therefore, I will focus on discussing the physical processes that could create multiphase structures within such outflows. We will also present synthetic ultraviolet and X-ray absorption spectra, which probe different outflow phases and can be used to test our model against observations.
