Probing the speed of gravity with LVK, LISA, and joint observations
Ian Harry, Johannes Noller
Theories of dark energy that affect the speed of gravitational waves on cosmological scales naturally lead to a frequency-dependent transition of that speed close to t…
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…
Black Hole Ringdown as a Probe for Dark Energy
Johannes Noller, Luca Santoni, Enrico Trincherini +1
Under the assumption that a dynamical scalar field is responsible for the current acceleration of the Universe, we explore the possibility of probing its physics in black hole merg…
Scale independent inflation
Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1
Weyl (scale) invariant theories of scalars and gravity can generate all mass scales spontaneously. In this paper we study a particularly simple version -- scale invariant gra…
A general theory of linear cosmological perturbations: stability conditions, the quasistatic limit and dynamics
Macarena Lagos, Emilio Bellini, Johannes Noller +2
We analyse cosmological perturbations around a homogeneous and isotropic background for scalar-tensor, vector-tensor and bimetric theories of gravity. Building on previous results,…
Gravitational Waves in Doubly Coupled Bigravity
Philippe Brax, Anne-Christine Davis, Johannes Noller
We consider gravitational waves from the point of view of both their production and their propagation in doubly coupled bigravity in the metric formalism. In bigravity, the two gra…
