Description of the research topic:
The recent sixfold detection of gravitational waves from both black hole
binaries and neutron star binaries opened up the era of gravitational wave
astronomy. These sources are characterised by a multitude of intrinsic (masses and spins) and extrinsic (localisation, orientation, distance) parameters. The two polarisations produced according to general relativity will combine into the signal weighted by detector-dependent antenna functions. Under certain symmetries a Helmholtz-like decomposition of gravitational perturbations leads to even and odd modes, propagating independently. The research topic is to derive them and analyse the emergence of gravitational wave signal as a combination of these contributions under various symmetries both in general relativity and in modified theories of gravity.
