Nahum Arav

Nahum Arav is a Professor in the Department of Physics at Virginia Polytechnic Institute and State University (Virginia Tech), affiliated with the College of Science. His research focuses on quasar outflows, active galactic nuclei (AGN) feedback, and high-energy astrophysical phenomena. He holds a Ph.D. from the University of Colorado.

His work investigates galactic-scale outflows from quasars, their impact on AGN feedback, and the interplay between accretion disks and outflow dynamics. Key projects include the AGN STORM initiative, which uses multi-wavelength observations (X-ray, UV, optical) to study objects like Mrk 817, and analyses of Hubble Space Telescope (HST) and VLT/UVES data to quantify outflow distances and energetics.

Recent studies emphasize outflow acceleration, metallicity, and the role of extreme UV observations in tracing AGN feedback mechanisms. His research bridges observational astronomy with theoretical models, addressing questions about black hole growth suppression and cosmic evolution.

Notable collaborations include the Space Telescope and Optical Reverberation Mapping Project (STORM), focusing on NGC 5548 and other AGN systems. His work highlights outflows' potential as primary contributors to AGN feedback, with implications for galaxy formation and evolution.
