Systematic bias in LISA ringdown analysis due to waveform inaccuracy
Lodovico Capuano, Massimo Vaglio, Rohit S. Chandramouli +3
Inaccurate modeling of gravitational-wave signals can introduce systematic biases in the inferred source parameters. As detector sensitivities improve and signals become louder, mi…

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…

Higher-derivative corrections to the Kerr quasinormal mode spectrum
Pablo A. Cano, Lodovico Capuano, Nicola Franchini +2
We provide the most complete analysis so far of quasinormal modes of rotating black holes in a general higher-derivative extension of Einstein's theory. By finding the corrections…
