What are the physical conditions around compact objects? How do they accelerate particles to the highest energies seen?

Professor Romani is interested in the physics of the most extreme objects in the observable universe—neutron stars and black holes—where density, gravitational field and, often, magnetic field reach their maximum measured values. His group makes observations of such objects, using premiere telescopes on the ground and in space, and constructs theoretical models to interpret the remarkable behaviors seen. One particular interest is studying how black holes and neutron stars accelerate particles to energies much higher than those yet produced on Earth and how they generate relativistic outflows in the form of winds and jets.

Current areas of focus:
- Populations of gamma-ray sources
- The origin and evolution of radio pulsars
- Supernovae and their products
- Instrumentation for fast optical variability
- Pulsar timing and gravity wave searches
