Theoretical research in astrophysics at Columbia is an active and exciting area, spanning a wide range of topics from the early universe to planetary atmospheres. Particular areas of focus include the electrodynamics of compact objects, gravitational dynamics, structure formation and cosmology, black hole formation and orbital dynamics, gravitational wave astronomy, accretion-disk physics, high-redshift star formation, reionization, planet formation, and planetary atmospheres. We stress the importance of interactions with both observational and numerical research.
