Direct Inference of Nuclear Equation-of-State Parameters from Gravitational-Wave Observations
Brendan T. Reed, Cassandra L. Armstrong, Rahul Somasundaram +4
The observation of neutron star mergers with gravitational waves (GWs) has provided a new method to constrain the dense-matter equation of state (EOS) and to better understand its…
Leveraging differentiable programming in the inverse problem of neutron stars
Thibeau Wouters, Peter T. H. Pang, Hauke Koehn +5
Neutron stars (NSs) probe the high-density regime of the nuclear equation of state (EOS). However, inferring the EOS from observations of NSs is a computationally challenging task.…
The impact of dark matter on tidal signatures in neutron star mergers with Einstein Telescope
Hauke Koehn, Edoardo Giangrandi, Nina Kunert +3
If dark matter (DM) accumulates inside neutron stars (NS), it changes their internal structure and causes a shift of the tidal deformability from the value predicted by the dense-m…
Kilonova Emissions from Neutron Star Merger Remnants: Implications for Nuclear Equation of State
Kelsey A. Lund, Rahul Somasundaram, Gail C. McLaughlin +3
Multi-messenger observation of binary neutron-star mergers can provide valuable information on the nuclear equation of state (EoS). Here, we investigate to which extent electromagn…
Probe and Prejudice: Classification of compact objects and model comparison using EOS knowledge
Hauke Koehn, Thibeau Wouters, Henrik Rose +4
Nuclear theory and experiments, alongside astrophysical observations, constrain the equation of state (EOS) of supranuclear-dense matter. Conversely, knowledge of the EOS allows an…
Towards accelerated nuclear-physics parameter estimation from binary neutron star mergers: Emulators for the Tolman-Oppenheimer-Volkoff equations
Brendan T. Reed, Rahul Somasundaram, Soumi De +5
Gravitational-wave observations of binary neutron-star (BNS) mergers have the potential to revolutionize our understanding of the nuclear equation of state (EOS) and the fundamenta…
Measuring Neutron Star Radius with second and third generation Gravitational Wave Detector Networks
Ananya Bandopadhyay, Keisi Kacanja, Rahul Somasundaram +2
The next generation of ground-based interferometric gravitational wave detectors will observe mergers of black holes and neutron stars throughout cosmic time. A large number of the…
