A New Multiwavelength Approach to Measuring Supermassive Black Hole Spin
Black hole spin is one of the primary factors that determine the behavior of supermassive black hole (SMBH) accretion disks in AGN. So far, SMBH spin measurements have primarily been made by measuring broadening in Fe Kα X-ray reflection emissions (6-7 keV); however, these results may be subject to high column densities near the ISCO of the SMBH mimicking spin effects. This work aims to circumvent this issue by modeling UV and Optical SEDs using QSOSED to measure the best-fit spin for an object of a given mass and Eddington accretion rate. We obtained UV and optical data from SWIFT and LCO for 20 low-redshift (z<0.5) AGN with Fe Kα spin measurements, which we compare to our best-fit results. We find that on average, X-ray reflection methods overestimate spin.

NANOGrav 15 year targeted search for continuous gravitational waves
Using the NANOGrav 15 year data along with enterprise MCMC and QuickCW codes to search for detections of continuous nHz gravitational waves (GWs) from SMBH binaries and place upper limits on GW frequency and mass on potential sources for non-detections.
