Searching for candidates of coalescing binary black holes formed through chemically homogeneous evolution in GWTC-3
Ying Qin, Yuan-Zhu Wang, Simone S. Bavera +10
The LIGO, Virgo, and KAGRA (LVK) collaboration has announced 90 coalescing binary black holes (BBHs) with to date, however, the origin of their formation cha…
The Hitchhiker's guide to the galaxy catalog approach for gravitational wave cosmology
Jonathan R. Gair, Archisman Ghosh, Rachel Gray +28
We outline the ``dark siren'' galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in the implement…
The TRAPUM L-band survey for pulsars in Fermi-LAT gamma-ray sources
C. J. Clark, R. P. Breton, E. D. Barr +35
More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of pulsar-li…
Aberration of gravitational waveforms by peculiar velocity
Camille Bonvin, Giulia Cusin, Cyril Pitrou +3
One key prediction of General Relativity is that gravitational waves are emitted with a pure spin-2 polarisation. Any extra polarisation mode, spin-1 or spin-0, is consequently con…
Third post-Newtonian effective-one-body Hamiltonian in scalar-tensor and Einstein-scalar-Gauss-Bonnet gravity
Félix-Louis Julié, Vishal Baibhav, Emanuele Berti +1
We build an effective-one-body (EOB) Hamiltonian at third post-Newtonian (3PN) order in scalar-tensor (ST) and Einstein-scalar-Gauss-Bonnet (ESGB) theories of gravity. The latter i…
Gravitational wave lensing as a probe of halo properties and dark matter
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Just like light, gravitational waves (GWs) are deflected and magnified by gravitational fields as they propagate through the Universe. However, their low frequency, phase coherence…
Friedmann equations and cosmic bounce in a modified cosmological scenario
Ana Alonso-Serrano, Marek Liška, Antonio Vicente-Becerril
In this work we present a derivation of modified Raychaudhuri and Friedmann equations from a phenomenological model of quantum gravity based on the thermodynamics of spacetime. Sta…
Numerical-relativity simulation for tidal disruption of white dwarfs by a supermassive black hole
Alan Tsz Lok Lam, Masaru Shibata, Kenta Kiuchi
We study tidal disruption of white dwarfs in elliptic orbits with the eccenticity of -- by a non-spinning supermassive black hole of mass in…
Tests of general relativity in the nonlinear regime: a parametrized plunge-merger-ringdown gravitational waveform model
Elisa Maggio, Hector O. Silva, Alessandra Buonanno +1
The plunge-merger stage of the binary-black hole coalescence, when the bodies' velocities reach a large fraction of the speed of light and the gravitational-wave luminosity peaks,…
Unified model for the LISA measurements and instrument simulations
Jean-Baptiste Bayle, Olaf Hartwig
LISA is a space-based mHz gravitational-wave observatory, with a planned launch in 2034. It is expected to be the first detector of its kind, and will present unique challenges in…
Actinide-boosting r Process in Black Hole-Neutron Star Merger Ejecta
Shinya Wanajo, Sho Fujibayashi, Kota Hayashi +3
We examine nucleosynthesis in the ejecta of black hole-neutron star mergers based on the results of long-term neutrino-radiation-magnetohydrodynamics simulations for the first time…
Emergence of quadratic gravity from entanglement equilibrium
Ana Alonso-Serrano, Marek Liška
In this work, we derive the linearised equations of quadratic gravity from entanglement equilibrium of local causal diamonds. Rather than starting from the Wald entropy prescriptio…
Improved binary black hole searches through better discrimination against noise transients
Sunil Choudhary, Sukanta Bose, Sanjeev Dhurandhar +1
Short-duration noise transients in LIGO and Virgo detectors significantly affect the search sensitivity of compact binary coalescence (CBC) signals, especially in the high mass reg…

Quentin Henry
We complete the computation of the gravitational waveform amplitude for non-spinning compact binaries to the third and a half post-Newtonian (PN) order in the quasi-circular case.…
How does dark matter affect compact star properties and high density constraints of strongly interacting matter
Violetta Sagun, Edoardo Giangrandi, Oleksii Ivanytskyi +2
We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution i…
Adapting to noise distribution shifts in flow-based gravitational-wave inference
Jonas Wildberger, Maximilian Dax, Stephen R. Green +5
Deep learning techniques for gravitational-wave parameter estimation have emerged as a fast alternative to standard samplers $\unicode{x2013}$ producing results of comparable accur…

F. Abbate, A. Possenti, A. Ridolfi +17
We present the polarization profiles of 22 pulsars in the globular cluster 47 Tucanae using observations from the MeerKAT radio telescope at UHF-band (544-1088 MHz) and report prec…
Quality over Quantity: Optimizing pulsar timing array analysis for stochastic and continuous gravitational wave signals
Lorenzo Speri, Nataliya K. Porayko, Mikel Falxa +4
The search for gravitational waves using Pulsar Timing Arrays (PTAs) is a computationally expensive complex analysis that involves source-specific noise studies. As more pulsars ar…
