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…
Positivity in the sky
Scott Melville, Johannes Noller
Positivity bounds - the consequences of requiring a unitary, causal, local UV completion - place strong restrictions on theories of dark energy and/or modified gravity. We derive a…
