Radial Solutions of Multi-Field de Sitter Galileons
Alice Garoffolo, Mary Gerhardinger, Kurt Hinterbichler +1
We study static, spherically symmetric screening solutions in the -invariant multi-field de Sitter Galileon theory, with matter couplings preserving the internal…
Wave-optics gravitational wave lensing in modified gravity
Alice Garoffolo, Gianmassimo Tasinato
We initiate the study of gravitational-wave lensing in the wave-optics regime within modified gravity. We consider a phenomenological setup in which the gravitational-wave amplitud…
Gravitational-wave lensing beyond rays: a disordered-system approach
Ripalta Amoruso, Ginevra Braga, Alice Garoffolo +3
We develop a framework to describe gravitational wave propagation through a stochastic distribution of weak gravitational lenses beyond the geometric optics limit. We model the len…
Testing gravitational wave polarizations with LISA
Shingo Akama, Maxence Corman, Paola C. M. Delgado +16
In this paper we quantify the ability of the Laser Interferometer Space Antenna (LISA) to test the presence of non-tensorial polarizations as well as modifications to the tensor on…
Scattering perspective on gravitational lensing
Mariana Carrillo Gonzalez, Valerio De Luca, Alice Garoffolo +2
Gravitational waves propagating across gravitational potentials undergo lensing effects that, in the wave-optics regime, manifest as frequency-dependent amplitude and phase modulat…
Multi-Galileons in Curved Space
Alice Garoffolo, Kurt Hinterbichler, Mark Trodden
Using the probe brane construction of higher derivative effective field theories, extended to higher co-dimensions and curved spaces, we construct galileon and DBI theories on de S…
Tidal Love numbers and Green's functions in black hole spacetimes
Valerio De Luca, Alice Garoffolo, Justin Khoury +1
Tidal interactions play a crucial role in deciphering gravitational wave signals emitted by the coalescence of binary systems. They are usually quantified by a set of complex coeff…
Proper time path integrals for gravitational waves: an improved wave optics framework
Ginevra Braga, Alice Garoffolo, Angelo Ricciardone +2
When gravitational waves travel from their source to an observer, they interact with matter structures along their path, causing distinct deformations in their waveforms. In this s…
Prospects of testing late-time cosmology with weak lensing of gravitational waves and galaxy surveys
Anna Balaudo, Alice Garoffolo, Matteo Martinelli +2
We investigate the synergy of upcoming galaxy surveys and gravitational wave (GW) experiments in constraining late-time cosmology, examining the cross-correlations between the weak…
Wave-optics limit of the stochastic gravitational wave background
Alice Garoffolo
The stochastic gravitational wave background (SGWB) is a rich resource of cosmological information, encoded both in its source statistics and anisotropies induced by propagation ef…
Unifying gravitational waves and dark energy
Alice Garoffolo, Omar Contigiani
We present a unifying treatment for metric and scalar perturbations across different energy regimes in scalar-tensor theories of gravity. To do so, we introduce two connected symme…
Gravitational-wave cosmological distances in scalar-tensor theories of gravity
Gianmassimo Tasinato, Alice Garoffolo, Daniele Bertacca +1
We analyze the propagation of high-frequency gravitational waves (GW) in scalar-tensor theories of gravity, with the aim of examining properties of cosmological distances as inferr…
Detecting Dark Energy Fluctuations with Gravitational Waves
Alice Garoffolo, Marco Raveri, Alessandra Silvestri +4
Luminosity distance estimates from electromagnetic and gravitational wave sources are generally different in models of dynamical dark energy and gravity beyond the standard cosmolo…
Gravitational waves and geometrical optics in scalar-tensor theories
Alice Garoffolo, Gianmassimo Tasinato, Carmelita Carbone +2
The detection of gravitational waves (GWs) propagating through cosmic structures can provide invaluable information on the geometry and content of our Universe, as well as on the f…
