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 interest is to find ways to blow up massive stars, that is, make core-collapse supernovae and gamma-ray bursts and their compact remnants, black holes and neutron stars. This work is carried out as part of the Simulating eXtreme Spacetimes (SXS) collaboration and we also work closely with the Einstein Toolkit team.

Another line of my research is concerned with the observation and interpretation of gravitational waves using the LIGO interferometers and I am a member of the LIGO Scientific Collaboration.

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

Trainees/Mentees that won National fellowships:
Evan O'Connor (Hubble 2014, PhD 2012), Christine Corbett Moran (NSF 2015), Philipp Mösta (Einstein 2015), Christian Reisswig (Einstein 2012), Luke Roberts (Einstein 2013).

Some background on me:
I received my PhD in 2007 at the Max Planck Institute for Gravitational Physics under Bernard Schutz's and Ed Seidel's supervision and then was a Joint Institute for Nuclear Astrophysics postdoctoral fellow with Adam Burrows at The University of Arizona before joining Caltech. More details can be found in my CV.

Research Opportunities

Senior Thesis:If you are a Caltech undergrad and interested in doing a senior thesis in Ay or Ph, please come see me! I am happy to advise senior thesis work and have a number of interesting projects available.
Prospective Summer Undergrads:We work with the LIGO REU program. Please see the projects and application procedures listed there. Caltech undergrads should contact me directly about SURF possibilities.
Prospective Grad Students: If you are interested in our research and would like to join us, please apply to the Caltech Astrophysics and/or the Caltech Physics graduate programs. Please do not send me your application materials -- these should go to the graduate program. The admission decision will be made by the graduate admission committees.
My group is actively trying to increase the representation of women and minorities in theoretical physics and astrophysics. We thus especially encourage women and minorities to apply.
