Efficient reanalysis of events from GWTC-3 with RIFT and asimov
D. Fernando, R. O'Shaughnessy, D. Williams
Different waveform models can yield notably different conclusions about the properties of individual gravitational wave events. For instance, previous analyses using the SEOBNRv4PH…
Adapting a novel framework for rapid inference of massive black hole binaries for LISA
Aasim Jan, Richard O'Shaughnessy, Deirdre Shoemaker +1
The Laser Interferometer Space Antenna (LISA) is designed to detect a variety of gravitational-wave events, including mergers of massive black hole binaries, stellar-mass black hol…
Inference on neutron star parameters and the nuclear equation of state with RIFT, using prior EOS information
Askold Vilkha, Anjali Yelikar, Richard O'Shaughnessy +1
In this paper, we present an inference method for determining neutron star parameters and constraining the nuclear equation of state (EOS) using the RIFT parameter inference engine…
Astrophysical assumptions and equation of state framework have larger impact on equation of state inference than individual neutron star observations
Atul Kedia, Richard O'Shaughnessy, Leslie Wade +1
The wide range of nuclear densities achieved in neutron stars makes them probes of dense nuclear behavior in the form of the nuclear equation of state (EoS). Studying neutron stars…
Waveform systematics in gravitational-wave inference of signals from binary neutron star merger models incorporating higher order modes information
A. B. Yelikar, R. O' Shaughnessy, J. Lange +1
Accurate information from gravitational wave signals from coalescing binary neutron stars provides essential input to downstream interpretations, including inference of the neutron…
Eccentricity matters: Impact of eccentricity on inferred binary black hole populations
Muhammad Zeeshan, Richard O'Shaughnessy
Gravitational waves (GW), emanating from binary black holes (BBH), encode vital information about their source. GW signals enable us to deduce key properties of the BBH population…
