I am interested in the approximate analytical description of binary compact
objects in general relativity and an application to gravitational wave astronomy.
More specifically, I am interested in the inclusion of the multipoles of the
compact objects, such as spin or quadrupole, into the post-Newtonian,
post-Minkowskian, and small mass ratio approximations. The spin effects
were completed recently to the fourth post-Newtonian order using an
effective field theory approach.
For the quadrupole case my investigations include dynamical tides, which become
important when the orbital motion is in resonance with an oscillation mode of the
(general relativistic) compact object. This is of particular interest for
neutron stars and I was granted a
DFG research fellowship for this project in the past.
More recently I am also working on the Effective One Body model for gravitational waveforms
from compact binaries at the Max Planck
Institute for Gravitational Physics (Albert Einstein Institute) in
the group for Astrophysical and Cosmological Relativity.
In this Effective One Body model, the results of the mentioned
approximations are incorporated synergetically, together with information from
full-fledged numerical simulations.
This makes it one of the most powerful tools to predict gravitational
waveforms for gravitational wave astronomy.
