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…
