GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Gravitational wave lensing: probing Fuzzy Dark Matter with LISA
Shashwat Singh, Guilherme Brando, Stefano Savastano +1
Gravitational lensing is a universal phenomenon: it affects both gravitational waves (GWs) and electromagnetic signals travelling through the gravitational field of a massive objec…
Gravitational wave propagation beyond General Relativity: geometric optic expansion and lens-induced dispersion
Nicola Menadeo, Miguel Zumalacárregui
The nature of gravity can be tested by how gravitational waves (GWs) are emitted, detected, and propagate through the universe. Propagation tests are powerful, as small deviations…
GLoW: novel methods for wave-optics phenomena in gravitational lensing
Hector Villarrubia-Rojo, Stefano Savastano, Miguel Zumalacárregui +4
Wave-optics phenomena in gravitational lensing occur when the signal's wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed…
Lens Stochastic Diffraction: A Signature of Compact Objects in Gravitational-Wave Data
Miguel Zumalacárregui
Every signal propagating through the universe is diffracted by the gravitational field of intervening objects, known as gravitational lenses. Diffraction is most efficient when cau…
Eikonal gravitational-wave lensing in Einstein-aether theory
Julius Streibert, Hector O. Silva, Miguel Zumalacárregui
Einstein-aether theory provides a model to test the validity of local Lorentz invariance in gravitational interactions. The speed of gravitational waves as measured from the binary…
Through the lens of Sgr A: identifying and resolving strongly lensed Continuous Gravitational Waves beyond the Einstein radius
Stefano Savastano, Filippo Vernizzi, Miguel Zumalacárregui
Lensed gravitational waves will offer new means to probe the distribution of matter in the universe, complementary to electromagnetic signals. Lensed continuous gravitational waves…
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…
Lensing of gravitational waves: efficient wave-optics methods and validation with symmetric lenses
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Gravitational wave (GW) astronomy offers the potential to probe the wave-optics regime of gravitational lensing. Wave optics (WO) effects are relevant at low frequencies, when the…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Theoretical priors in scalar-tensor cosmologies: Shift-symmetric Horndeski models
Dina Traykova, Emilio Bellini, Pedro G. Ferreira +3
Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric…
Field redefinitions in theories beyond Einstein gravity using the language of differential forms
Jose María Ezquiaga, Juan García-Bellido, Miguel Zumalacárregui
We study the role of field redefinitions in general scalar-tensor theories. In particular, we first focus on the class of field redefinitions linear in the spin-2 field and involvi…
Shaken, not stirred: kinetic mixing in scalar-tensor theories of gravity
Dario Bettoni, Miguel Zumalacárregui
Kinetic mixing between the metric and scalar degrees of freedom is an essential ingredient in contemporary scalar-tensor theories. This often makes hard to understand their physica…
Transforming gravity: from derivative couplings to matter to second-order scalar-tensor theories beyond the Horndeski Lagrangian
Miguel Zumalacárregui, Juan García-Bellido
We study the structure of scalar-tensor theories of gravity based on derivative couplings between the scalar and the matter degrees of freedom introduced through an effective metri…
