Biography
Martin Bourne is a theoretical astrophysicist specializing in the study of supermassive black holes and their influence on galaxy evolution. As of September 2024 Martin holds a UKRI Stephen Hawking Fellowship and is a Senior Lecturer based at the Centre for Astrophysics Research at the University of Hertfordshire. Prior to this, he was a Research Associate at the Kavli Institute for Cosmology and Institute of Astronomy at the University of Cambridge (2015-2020 & 2022-2024). Martin obtained his PhD from the University of Leicester (2012-2015) and completed his undergraduate studies in Physics at the University of Oxford (2006-2010). He additionally has a background in science education having completed a PGCE at the University of Bath (2012) and has industry experience having spent nearly two years working as a software developer.
Research
Martin Bourne's primary research focuses on various aspects of supermassive black hole physics from the event horizon to the cosmic web. He has a particular interest in developing new models and techniques to capture accretion and feedback processes (winds and jets) in both small (e.g. black hole binaries and circumbinary discs) and large-scale (cosmological) simulations in order to understand their impact on galaxy evolution, cosmology and multi-messenger astronomy. Martin is a long-time developer of the Arepo code, and is also a member of several national and international collaborations including the Lisa Consortium (space-based gravitational wave detector), X-Gap (an XMM-Newton project to study hot gas in groups) and the SEEDZ Project (simulation project studying high redshift black hole formation).
