When the Ringing Stops: Purely Imaginary Modes in the Ringdown Spectrum of Dynamical Black Holes
Lodovico Capuano, Thomas Lovo, Gorka Prieto-Varela +4
We extend the frequency-domain analysis of quasinormal modes in a dynamical, spherically symmetric black hole spacetime undergoing constant-rate mass evolution. In particular, we r…
Scalar emission from binary neutron stars in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Thiago Assumpcao +2
We investigate the scalar emission from binary neutron stars in shift-symmetric scalar-tensor theories with kinetic screening (-essence), using 3+1 numerical simulations in the…
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…
Searching for Gravitational Waves with Gaia and its Cross-Correlation with PTA: Absolute vs Relative Astrometry
Massimo Vaglio, Mikel Falxa, Giorgio Mentasti +5
Astrometric missions like Gaia provide exceptionally precise measurements of stellar positions and proper motions. Gravitational waves traveling between the observer and distant st…
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…
Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Miguel Bezares +1
We explore scalar radiation from neutron star-black hole binaries in scalar-tensor theories with kinetic screening (-essence). Using 3+1 numerical relativity simulations in the…
Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array
Clemente Smarra, Adrien Kuntz, Enrico Barausse +15
Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telesco…
Nonlinear quasinormal mode detectability with next-generation gravitational wave detectors
Sophia Yi, Adrien Kuntz, Enrico Barausse +4
In the aftermath of a binary black hole merger event, the gravitational wave signal emitted by the remnant black hole is modeled as a superposition of damped sinusoids known as qua…
Angular momentum sensitivities in scalar-tensor theories
Adrien Kuntz, Enrico Barausse
Scalar-tensor theories have a long history as possible phenomenological alternatives to General Relativity, but are known to potentially produce deviations from the (strong) equiva…
