Kevin Marshall

Kevin Marshall serves as Chair of Physics and Astronomy and Associate Professor at Widener University, where he is designated a Media Expert in Technology. He operates within the Physics (BS) program and maintains an office in Kirkbride Hall Room 266B.

Education:

• PhD in Astronomy (2006), Georgia State University (GA)

Research Interests:
Dr. Marshall specializes in high-energy variability of active galactic nuclei (AGN), focusing on supermassive black holes that emit tremendous radiation as matter accretes. His work analyzes X-ray and gamma-ray emissions from inner regions near black holes, using brightness variability to constrain physical parameters and geometry of accretion systems. He employs multiwavelength observational techniques and time-domain analysis to study phenomena including radio-loud narrow-line Seyfert 1 galaxies and broad-line radio galaxies.

Publication Trends:
His 2008-2014 publications reveal consistent focus on AGN variability through multiwavelength correlations, particularly examining sources like Markarian 509 and 3C 120. The research demonstrates expertise in connecting X-ray/optical fluctuations to black hole accretion physics, with emphasis on time-domain astronomy and high-energy processes. These works collectively advance understanding of supermassive black hole environments through rigorous observational analysis.
