Radial Perturbations of Black Holes in DHOST Theories
Christos Charmousis, Simon Iteanu, David Langlois +1
We study radial perturbations of static black holes with primary hair in a subfamily of degenerate higher-order scalar-tensor (DHOST) theories. We recast the equation of motion for…

Axial perturbations of black holes with primary scalar hair
Christos Charmousis, Simon Iteanu, David Langlois +1
We study axial perturbations of static black holes with primary hair in a family of degenerate higher-order scalar-tensor (DHOST) theories. These solutions possess a scalar charge,…

Vanishing of Quadratic Love Numbers of Schwarzschild Black Holes
Simon Iteanu, Massimiliano Maria Riva, Luca Santoni +2
The induced conservative tidal response of self-gravitating objects in general relativity is parametrized in terms of a set of coefficients, which are commonly referred to as Love…
