cloelib: A Flexible Python Library for Computing Cosmological Observables in the Euclid Era
Marco Bonici, Guadalupe Cañas-Herrera, Pedro Carrilho +54
cloelib is a Python library developed to compute cosmological observables within the Cosmology Likelihood for Observables in Euclid (CLOE) ecosystem (cloe-org). As cosmology enters…
Across the Universe: GW231123 as a magnified and diffracted black hole merger
Srashti Goyal, Hector Villarrubia-Rojo, Miguel Zumalacarregui
GW231123 appears as the most massive binary black hole (BBH) ever observed by the LIGO interferometers with total mass . A high observed mass can be explained by t…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
Euclid Quick Data Release (Q1). The first catalogue of strong-lensing galaxy clusters
Euclid Collaboration, P. Bergamini, M. Meneghetti +375
We present the first catalogue of strong lensing galaxy clusters identified in the Euclid Quick Release 1 observations (covering ). This catalogue is the resu…
Euclid Quick Data Release (Q1). The Strong Lensing Discovery Engine E -- Ensemble classification of strong gravitational lenses: lessons for Data Release 1
Euclid Collaboration, P. Holloway, A. Verma +343
The Euclid Wide Survey (EWS) is expected to identify of order galaxy-galaxy strong lenses across deg. The Euclid Quick Data Release (Q1) of deg Eu…
Euclid Quick Data Release (Q1): The Strong Lensing Discovery Engine A -- System overview and lens catalogue
Euclid Collaboration, M. Walmsley, P. Holloway +372
We present a catalogue of 497 galaxy-galaxy strong lenses in the Euclid Quick Release 1 data (63 deg). In the initial 0.45\% of Euclid's surveys, we double the total number of…
Reconstructing the dark energy density in light of DESI BAO observations
Maria Berti, Emilio Bellini, Camille Bonvin +3
In light of the evidence for dynamical dark energy (DE) found from the most recent Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BAO) measurements, we pe…
Euclid Quick Data Release (Q1). The Strong Lensing Discovery Engine C: Finding lenses with machine learning
Euclid Collaboration, N. E. P. Lines, T. E. Collett +350
Strong gravitational lensing has the potential to provide a powerful probe of astrophysics and cosmology, but fewer than 1000 strong lenses have been confirmed so far. With a 0.16'…
To the Problem of Cosmic Expansion in Massive Gravity
Lavinia Heisenberg, Alessandro Longo, Giovanni Tambalo +1
We consider evolving, spatially flat isotropic and homogeneous (FLRW) cosmologies in ghost-free (dRGT) massive gravity. In this theory, no dynamical flat FLRW background exists if…
wolensing: A Python package for computing the amplification factor for gravitational waves with wave-optics effects
Simon M. C. Yeung, Mark H. Y. Cheung, Miguel Zumalacarregui +1
The wolensing Python package offers a solution for gravitational wave lensing computations within the full wave-optics regime. This tool is primarily designed to calculate the grav…
Probing minihalo lenses with diffracted gravitational waves
Mark Ho-Yeuk Cheung, Ken K. Y. Ng, Miguel Zumalacárregui +1
When gravitational waves pass near a gravitating object, they are deflected, or lensed. If the object is massive, such that the wavelength of the waves is small compared to its gra…
Probing general relativistic spin-orbit coupling with gravitational waves from hierarchical triple systems
Marius A. Oancea, Richard Stiskalek, Miguel Zumalacárregui
Wave packets propagating in inhomogeneous media experience a coupling between internal and external degrees of freedom and, as a consequence, follow spin-dependent trajectories. Th…
Weakly Lensed Gravitational Waves: Probing Cosmic Structures with Wave-Optics Features
Stefano Savastano, Giovanni Tambalo, Hector Villarrubia-Rojo +1
Every signal propagating through the universe is at least weakly lensed by the intervening gravitational field. In some situations, wave-optics phenomena (diffraction, interference…
Probing lens-induced gravitational-wave birefringence as a test of general relativity
Srashti Goyal, Aditya Vijaykumar, Jose Maria Ezquiaga +1
Theories beyond general relativity (GR) modify the propagation of gravitational waves (GWs). In some, inhomogeneities (aka. gravitational lenses) allow interactions between the met…
Frequency- and polarization-dependent lensing of gravitational waves in strong gravitational fields
Marius A. Oancea, Richard Stiskalek, Miguel Zumalacárregui
The propagation of gravitational waves can be described in terms of null geodesics by using the geometrical optics approximation. However, at large but finite frequencies the propa…

Vicky Kalogera, B. S. Sathyaprakash, Matthew Bailes +88
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptiona…
Fully relativistic predictions in Horndeski gravity from standard Newtonian N-body simulations
Guilherme Brando, Kazuya Koyama, David Wands +3
The N-body gauge allows the introduction of relativistic effects in Newtonian cosmological simulations. Here we extend this framework to general Horndeski gravity theories, and inv…
Gravitational wave lensing beyond general relativity: birefringence, echoes and shadows
