Consistency relations for large-scale structure in modified gravity and the matter bispectrum
Marco Crisostomi, Matthew Lewandowski, Filippo Vernizzi
We study perturbation theory for large-scale structure in the most general scalar-tensor theories propagating a single scalar degree of freedom, which include Horndeski theories an…
Perturbations of a rotating black hole in DHOST theories
Christos Charmousis, Marco Crisostomi, David Langlois +1
We study linear perturbations of a rotating black hole solution that has been recently discovered in degenerate higher-order scalar-tensor (DHOST) theories. We find a parametrizati…
Testing modified gravity at cosmological distances with LISA standard sirens
E. Belgacem, G. Calcagni, M. Crisostomi +18
Modifications of General Relativity leave their imprint both on the cosmic expansion history through a non-trivial dark energy equation of state, and on the evolution of cosmologic…
Rotating Black Holes in Higher Order Gravity
Christos Charmousis, Marco Crisostomi, Ruth Gregory +1
We develop a new technique for finding black hole solutions in modified gravity that have "stealth" hair, i.e., hair whose only gravitational effect is to tune the cosmological con…
Vainshtein regime in Scalar-Tensor gravity: constraints on DHOST theories
Marco Crisostomi, Matthew Lewandowski, Filippo Vernizzi
We study the screening mechanism in the most general scalar-tensor theories that leave gravitational waves unaffected and are thus compatible with recent LIGO/Virgo observations. U…
