Research Homepage of Christian D. Ott


I am a computational/theoretical astrophysicist in TAPIR, which is part of the Walter Burke Institute for Theoretical Physics at Caltech, working at the interface of numerical relativity, nuclear/neutrino astrophysics, and gravitational-wave physics. My current primary research interests are (1) explosions of massive stars in core-collapse supernovae and long gamma-ray bursts and their multi-messenger signatures in neutrinos, gravitational waves, and photons, (2) the formation of stellar mass and supermassive black holes, and (3) binary black hole and neutron star mergers.

I lead the Caltech portion of the Simulating eXtreme Spacetimes (SXS) collaboration and also work closely with the Einstein Toolkit team.

Another line of my research is concerned with the observation and interpretation of gravitational waves from astrophysical sources. I was involved in the LIGO Scientific Collaboration and contributed to the first direct detection of gravitational waves.

I am presently leading an NSF CAREER project in Gravitational Physics. I was a 2012-2014 Alfred P. Sloan Research Fellow.
