About
Martin Haas is an astronomer whose research bridges observational techniques in active galactic nuclei (AGN) physics and large-scale photometric surveys of the Galactic disk. His most influential contributions center on photometric reverberation mapping, a powerful and efficient method for measuring the size of the broad-line region (BLR) in AGN, determining supermassive black hole masses, and isolating host-subtracted AGN luminosities — work that has garnered nearly 100 citations since its 2011 publication. Haas has applied these techniques to individual AGN systems including 3C 120, ESO 399-IG20, PGC 50427, and WPVS48, systematically probing both BLR sizes and dust torus structure using robotic telescopes operated by the Universitätssternwarte Bochum (USB) near Cerro Armazones in Chile. Beyond AGN studies, Haas has led the Bochum Galactic Disk Survey, a multi-year monitoring campaign covering the southern Galactic plane to detect variable stars and eclipsing high-mass binaries. His team's development and deployment of innovative robotic telescope infrastructure — including the 40 cm Bochum Monitoring Telescope and a solar-powered observatory — underscores a career dedicated to advancing observational astronomy through creative instrumentation and long-term systematic monitoring.
