Enhancing gravitational waveform models through dynamic calibration
Yoshinta Eka Setyawati, Frank Ohme, Sebastian Khan
Strategies to model the inspiral, merger and ringdown gravitational waveform of coalescing binaries are restricted in parameter space by the coverage of available numerical-relativ…
Phenomenological model for the gravitational-wave signal from precessing binary black holes with two-spin effects
Sebastian Khan, Katerina Chatziioannou, Mark Hannam +1
The properties of compact binaries, such as masses and spins, are imprinted in the gravitational-waves they emit and can be measured using parameterised waveform models. Accurately…
Relevance of tidal effects and post-merger dynamics for binary neutron star parameter estimation
Reetika Dudi, Francesco Pannarale, Tim Dietrich +4
Measurements of the properties of binary neutron star systems from gravitational-wave observations require accurate theoretical models for such signals. However, current models are…
Constraining the Neutron Star Radius with Joint Gravitational-Wave and Short Gamma-Ray Burst Observations of Neutron Star-Black Hole Coalescing Binaries
Stefano Ascenzi, Nicola De Lillo, Carl-Johan Haster +2
Coalescing neutron star (NS)-black hole (BH) binaries are promising sources of gravitational-waves (GWs) to be detected within the next few years by current GW observatories. If th…
Matter imprints in waveform models for neutron star binaries: tidal and self-spin effects
Tim Dietrich, Sebastian Khan, Reetika Dudi +16
The combined observation of gravitational and electromagnetic waves from the coalescence of two neutron stars marks the beginning of multi-messenger astronomy with gravitational wa…
