Rate My Professor David Ballantyne

Ballantyne specializes in high-energy astrophysics, with research interests in the physics of accretion disks around black holes and neutron stars, and the co-evolution of galaxies and supermassive black holes. He develops computer models to interpret observations from X-ray, radio, and infrared telescopes, focusing on spectral features in active galactic nuclei and X-ray bursts from neutron stars. Key publications include Ghobadi, Ballantyne, & Bogdanovi'c (2026) "Evolution of Supermassive Black Hole Pairs on Inclined Orbits in Post-Merger Galaxies" (ApJ); Boztepe et al. (2025) "The 2020 Superburst of 4U 1608-522 and its impact on the accretion disk" (MNRAS); Li et al. (2025) "Dense matter in neutron stars with eXTP" (Science China Physics, Mechanics & Astronomy); Malewicz et al. (2025) "X-ray Reflection Signatures of Supermassive Black Hole Binaries" (ApJ); and Ballantyne (2023) "Radiation Driven Warping of Accretion Discs Due to X-ray Bursts" (MNRAS). He has authored over 100 papers, with an h-index of 58 and more than 13,000 citations. Ballantyne received NASA Group Achievement Awards for the NuSTAR Extragalactic Survey Team (2016) and NuSTAR Science Team (2015), along with early-career fellowships such as the NSERC Postdoctoral Fellowship (2002) and Theoretical Astrophysics Prize Fellowship at Arizona (2005). He has given invited talks at numerous international workshops and colloquia, served on extensive committees at Georgia Tech including the Astrophysics Major Committee, and co-edited the Active Galactic Nuclei chapter in the LSST Science Book (2009).
