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…
Scalar Cherenkov radiation from high-energy cosmic rays
Charles Dalang, Pierre Fleury, Lucas Lombriser
As first noted by Robert Wagoner in the 1970s, if a scalar field is nonminimally coupled to the Ricci scalar and propagates at subluminal speeds, then there exists the possibility…
Gravitational lenses in arbitrary space-times
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
The precision reached by current and forthcoming strong-lensing observations requires to accurately model various perturbations to the main deflector. Hitherto, theoretical models…
Scalar and tensor gravitational waves
Charles Dalang, Pierre Fleury, Lucas Lombriser
In dark-energy models where a scalar field is nonminimally coupled to the spacetime geometry, gravitational waves are expected to be supplemented with a scalar mode. Such scalar wa…
Horndeski gravity and standard sirens
Charles Dalang, Pierre Fleury, Lucas Lombriser
Standard sirens have been proposed as probes of alternative theories of gravity, such as Horndeski models. Hitherto, all studies have been conducted on a homogeneous-isotropic cosm…
Gravitation: from Newton to Einstein
Pierre Fleury
This document gathers the notes of a 30-hour review course on gravitation, which I delivered in January 2018 and January 2019 at the African Institute for Mathematical Sciences of…
