About

K. C. Steenbrugge is an astrophysicist specializing in active galactic nuclei (AGN) and reverberation mapping—a technique that uses light echoes to probe the innermost regions of distant galaxies. Their major contributions center on measuring the size, shape, and structure of the broad-line region (BLR) and the surrounding dust torus in Seyfert galaxies. Using robotic telescopes at Cerro Armazones in Chile, Steenbrugge led multi-year photometric monitoring campaigns that achieved unprecedented temporal sampling. Their work on 3C 120 (51 citations) demonstrated the power of small-aperture telescopes for AGN science, while studies of ESO 399-IG20 (29 citations) revealed a disk-like BLR geometry. The three-year campaign on PGC 50427 (23 citations) simultaneously mapped both the BLR and dust torus, providing key constraints on the AGN unified model. Their dust reverberation mapping of WPVS48 (16 citations) further refined torus sizes. By combining broad- and narrow-band optical filters with near-infrared observations, Steenbrugge has advanced our understanding of how gas and dust are distributed around supermassive black holes, enabling more accurate black hole mass measurements and offering critical tests of AGN structure models.
