Title: Through the Kaleidoscope: Applying Temporal and Multiwavelength Datasets to Supermassive Black Hole Phenomenology

Abstract: Active galactic nuclei provide unique laboratories for violent physical processes like stellar tidal disruption, highly relativistic jets, and turbulent accretion flows. A thorough understanding of these objects and their profound effect on galaxy evolution now depends upon synthesizing observations across many wavelengths and understanding their time evolution. In particular, high-resolution radio imaging surveys of outflows and star formation and timing observations with breakthrough instruments like the Kepler and TESS exoplanet-hunting missions have provided new intersectional insights and promise a fertile new temporal phase space for exploring the detailed phenomenology and cosmological implications of AGN. In my talk, I will discuss the 22 GHz radio survey of 268 radio-quiet BAT AGN and implications for both the origin of radio emission in non-jetted objects and galaxy-wide star formation suppression. I will also discuss time domain results in accretion physics and binary AGN from the Kepler and TESS AGN samples, as well as theoretical implications for observed properties of quasi-periodic oscillations. 

About the speaker: Dr. Smith grew up in the North Texas area around Dallas. She got her bachelor's of science in Astronomy from the University of Texas at Austin before moving on to the University of Maryland, where she earned her Masters and PhD in Astronomy jointly under Prof. Richard Mushotzky and as a NASA Earth and Space Sciences Fellow at the NASA Goddard Space Flight Center. She then moved on to an Einstein Postdoctoral Fellowship at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University. In August of 2020, she began her new position as an Assistant Professor of Physics at Southern Methodist University in Dallas, back in her hometown.
