Gravitational Wave Bias in IllustrisTNG300 from Machine-Learned Population-Synthesis Calibrated Merger Rates
Dorsa Sadat Hosseini, Taisiia Karasova, Nikshay Chugh +2
The large scale clustering of gravitational wave (GW) sources offers an independent probe of cosmology and compact-binary astrophysics. Interpreting future GW clustering measuremen…
Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys
Dorsa Sadat Hosseini, Amir Dehghani, J. Leo Kim +3
We present a framework for relating gravitational wave (GW) sources to the astrophysical properties of spectroscopic galaxy samples. We show how this can enable using clustering me…
Inference of Hubble constant using standard sirens and reconstructed matter density field
Supranta S. Boruah, Ghazal Geshnizjani, Guilhem Lavaux
We summarise a new approach for measuring the Hubble constant using standard sirens and the reconstructed matter density field obtained from observed galaxy surveys. Specifically,…
How Much NEC Breaking Can the Universe Endure?
Elly Moghtaderi, Brayden R. Hull, Jerome Quintin +1
Quantum fields can notoriously violate the null energy condition (NEC). In a cosmological context, NEC violation can lead to, e.g., dark energy at late times with an equation-of-st…
Cuscuton Bounce Beyond the Linear Regime: Bispectrum and Strong Coupling Constraints
Amir Dehghani, Ghazal Geshnizjani, Jerome Quintin
Cuscuton Gravity is characterized as a scalar field that can be added to general relativity without introducing any new dynamical degrees of freedom on a cosmological background. Y…
The Gravitational Wave Bias Parameter from Angular Power Spectra: Bridging Between Galaxies and Binary Black Holes
Amir Dehghani, J. Leo Kim, Dorsa Sadat Hosseini +3
This study presents the modeling of the gravitational wave (GW) bias parameter by bridging a connection between simulated GW sources and galaxies in low redshift galaxy surveys 2MP…
