About

C. Villforth is an astrophysicist specializing in the study of supermassive black holes and their host galaxies, with a particular focus on active galactic nuclei (AGN) and reverberation mapping. Their major contributions center on using robotic telescope networks to perform time-domain studies of AGN, enabling precise measurements of black hole masses and accretion disk structures. Villforth led the Las Cumbres Observatory Global Telescope (LCOGT) AGN Key Project, pioneering robotic reverberation mapping techniques that allow for continuous, long-duration monitoring of variable AGN. Their work on Arp 151 (15 citations) established the feasibility of robotic reverberation mapping, while studies of 3C 120 (11 citations) extended these techniques to broad-line radio galaxies. Most notably, their 2025 echo mapping campaign on NGC 7469 (9 citations) provided critical constraints on accretion disk temperature profiles, testing the theoretical prediction that disk sizes scale with wavelength as τ ∝ λ^(4/3). Villforth’s research has significantly advanced our understanding of black hole accretion physics, demonstrating how robotic observatories can revolutionize time-domain astrophysics by enabling sustained, high-cadence monitoring campaigns that were previously impractical with traditional telescope scheduling.
