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…
Measuring the propagation speed of gravitational waves with LISA
Tessa Baker, Gianluca Calcagni, Anson Chen +8
The propagation speed of gravitational waves, , has been tightly constrained by the binary neutron star merger GW170817 and its electromagnetic counterpart, under the assumpti…
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…
The effect of screening mechanisms on black hole binary inspiral waveforms
Cyril Renevey, Ryan McManus, Charles Dalang +1
Scalar-tensor theories leaving significant modifications of gravity at cosmological scales rely on screening mechanisms to recover General Relativity (GR) in high-density regions a…
Exploring the self-tuning of the cosmological constant from Planck mass variation
Daniel Sobral-Blanco, Lucas Lombriser
Recently, the variation of the Planck mass in the General Relativistic Einstein-Hilbert action was proposed as a self-tuning mechanism of the cosmological constant, preventing Stan…
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…
