Professor Christian Knigge serves as Professor of Astrophysics at the University of Southampton and is a core member of the Southampton Theory Astrophysics and Gravity (STAG) Research Centre within the Institute for Life Sciences. His research program investigates accretion phenomena across diverse cosmic scales, from stellar-mass compact objects to supermassive black holes.
Knigge's primary research focuses on accretion phenomena and associated outflows, cataclysmic variables, close binaries, globular clusters, and active galactic nuclei. He examines the physical mechanisms driving accretion disk instabilities, outflow generation, and explosive events in binary systems, with particular emphasis on white dwarf and black hole accretors. His work integrates observational data with theoretical modeling to unravel the complex physics of these high-energy environments.
Recent publications (2024-2025) reveal a strong emphasis on multi-wavelength observational campaigns, especially leveraging JWST capabilities, alongside theoretical code development. Key research threads include characterizing disk winds in active galactic nuclei, identifying quasi-periodic oscillations in white dwarf systems, classifying optical outbursts in cataclysmic variables, and developing computational tools like the SIROCCO radiative transfer code. These studies demonstrate his leadership in connecting observational signatures with fundamental accretion physics across different astrophysical regimes.
- Supervision: Currently guides six PhD students in Physics (Austen George William Wallis, Cordelia Brown, Brian Luff, Zackery Alexander Irving, Arianna Clarissa Albayati, Pornisara Nuchvanichakul)
- Grants: Leads STFC-funded projects including 'Line-Driven Disk Winds in Active Galactic Nuclei', 'C Knigge - Astrophysics at Southampton', and previously held a Leverhulme Trust Research Fellowship for 'The Universal Nature of Accreting Compact Objects'
As an integral member of the STAG Research Centre, Knigge collaborates within a multidisciplinary team investigating gravity-dominated systems, contributing to Southampton's prominence in theoretical and observational astrophysics through both individual research initiatives and institutional consolidation grants.
