Dr. Irwin uses X-ray satellite observatories to investigate the nature of galaxies, clusters of galaxies, and compact stellar remnants (neutron stars and black holes) accreting matter from neighboring stars in binary stellar systems.
Research Interests:
- Hot Gas Around Supermassive Black Holes
- X-ray Binary Populations of Galaxies
- Ultraluminous X-ray Sources
- Intermediate-Mass black holes
- X-ray Emission From Hot Gas in Early-type Galaxies
- Clusters/Groups of Galaxies
Current and Recent Research Projects:
- The Flow of Gas Within the Bondi Radius of a Supermassive Black Hole
- Searching for Evidence for Intermediate-mass Black Holes (IMBHs) in Globular Clusters from the Tidal Disruption of Passing Stars in the Cluster
- Identifying High Mass Concentrations on the Galaxy/Group Scale With Gravitational Lensing
