Paul Callanan

Paul Callanan is a Professor of Physics at University College Cork, specializing in multiwavelength studies of compact objects. His research examines black hole and neutron star binaries using X-ray, optical, and IR observations to measure masses, accretion dynamics, and galactic distributions. He has served on NASA/ESA review committees and conducts observations at international facilities like the Keck Observatory.

Callanan restored the historic Crawford Observatory at UCC and chairs the Royal Irish Academy's Astronomy Committee. His research addresses fundamental questions about black hole signatures, accretion disk evolution, and compact object populations in the Milky Way.
