Project description
Gravitational-wave observations using more accurate waveforms
The study of gravitational waves has deepened our understanding of stellar phenomena such as binary black holes and neutron stars, driving major breakthroughs across physics and astronomy. However, gravitational-wave (GW) signals are often weaker than background noise in detectors, making them difficult to identify and challenging to analyse due to the need for highly accurate waveforms. Supported by the Marie Skłodowska-Curie Actions programme, the AccModBinary project aims to improve both the detection and parameter inference of GW signals by developing more precise waveforms for increasingly sensitive detectors. To achieve this, it will refine the analytical description of compact binary dynamics within both general relativity and modified gravity theories.
Objective
Gravitational-wave (GW) observations have revolutionized our understanding of binary black holes and neutron stars. Since GW signals are typically weaker than the noise in the detectors, searching for GW signals and inferring their parameters requires accurate waveforms. The goal of this project to improve the analytical description of compact binary dynamics in general relativity and modified gravity theories, through the following related objectives: 1) deriving post-Newtonian results for the dissipative dynamics of spinning binaries, 2) developing the foundations of an effective-one-body waveform model for precessing spins in generic orbits, 3) modeling dynamical scalarization in Einstein-scalar-Gauss-Bonnet gravity to facilitate theory-specific searches for deviations from general relativity, and 4) complement gravitational self-force results with post-Newtonian information to model extreme mass-ratio inspirals in generic orbits. The results of this project will yield more accurate waveforms that are crucial for the increasing sensitivity of the LIGO-Virgo-KAGRA detectors and for future detectors, such as the Einstein telescope and the Laser Interferometer Space Antenna.
