The story
My visiting X-ray research at Curtin later connected with this wider collaboration. The paper analyses Chandra observations to catalogue exceptionally luminous X-ray sources in spiral galaxies.
A finding to take away
The survey identifies about 80 ultraluminous X-ray sources across 75 galaxies. The observed population is broadly consistent with models linking X-ray binaries to stellar mass and star formation, while individual bright sources still require careful interpretation.
The paper describes the full survey teamโs work; my contribution is part of that collaboration, not ownership of the entire catalogue.
