Jeffrey A. Hodgson

Jeffrey A. Hodgson is a Professor in the Department of Physics and Astronomy at Sejong University, specializing in high-resolution radio astronomy through Very Long Baseline Interferometry (VLBI) techniques. His research focuses on parsec-scale structures in active galactic nuclei, particularly examining jet dynamics, magnetic field configurations, and alignment phenomena between jets and their host galaxies.

Dr. Hodgson's primary research interests include:

• Very Long Baseline Interferometry observations of extragalactic sources
• Structure and dynamics of active galactic nuclei jets
• Magnetic field configurations in galactic cores
• Radio spectrum analysis of blazars and compact extragalactic sources
• Alignment phenomena between AGN jets and their host galaxies
• Polarimetric studies of jet structures

His recent publications demonstrate a consistent focus on using global VLBI networks to study parsec-scale phenomena in active galaxies. The research shows strong international collaboration patterns with scientists across multiple continents, reflecting the global nature of modern radio astronomy. His work frequently appears in top-tier astrophysics journals including Nature Astronomy, Astrophysical Journal, and Astronomy & Astrophysics, with significant citation impact as indicated by his h-index of 18.

Dr. Hodgson maintains an active research program with consistent publication output, showing 67 total research outputs with sustained productivity over the past decade. His 2024-2025 publications particularly focus on jet morphology in sources like 3C 84, NGC 315, and Mrk 421, revealing new insights into jet physics and magnetic field structures at unprecedented resolutions.
