TEOBResumS: an advanced waveform model for O4 — •Rossella Gamba — Friedrich-Schiller-Universität Jena, Jena, Germany

The detection of Gravitational Waves by LIGO and Virgo opened a new, exceptional avenue for studying the physics of binary systems of compact objects, such as black holes and neutron stars. Source properties can be extracted from the LIGO/Virgo data via matched filtering techniques that employ waveform templates, i.e. theoretical models of the gravitational waves (GWs) emitted by the two coalescing bodies. To be able to obtain the largest amount of information from the data, such models must incorporate a large amount of physics while retaining high faithfulness to waveforms from numerical relativity simulations. In this talk I will present TEOBResumS, an efficient state-of-the-art waveform model for GWs from generic binary systems. I will detail the physics included, highlight its computational efficiency and faithfulness and show applications to real and simulated data in view of the fourth observing run O4, planned for late 2022.
