Looking for non-gaussianity in Pulsar Timing Arrays through the four point correlator
Adrien Kuntz, Clemente Smarra, Massimo Vaglio
Pulsar Timing Arrays have recently reported strong evidence for a stochastic gravitational wave background. In standard analyses, it is modeled through pulsar-dependent Fourier coe…

Probing supermassive black hole scalarization with Pulsar Timing Arrays
Clemente Smarra, Lodovico Capuano, Adrien Kuntz
Scalar-tensor theories with a scalar field coupled to the Gauss-Bonnet invariant can evade no-hair theorems and allow for non-trivial scalar profiles around black holes. This coupl…
