Professor of Physics and Astronomy, University of Iowa

Kaaret's main interest is understanding the intense gravitational fields surrounding black holes and neutron stars and the dynamics of the accretion of matter onto these objects. He conducts observations at X-ray, optical, and radio wavelengths of objects in our Milky Way galaxy and in external galaxies. His current work concerns the highly luminous X-ray sources in nearby galaxies which have been interpreted as being intermediate-mass or "medium-sized" black holes, jet ejection from black holes, and the properties of X-ray binaries in the early universe. He also builds instrumentation for space-based X-ray astronomy and ground-based gamma-ray astronomy.
