Inferring black hole formation channels in GWTC-4.0 via parametric mass-spin correlations derived from first principles
Emanuele Berti, Francesco Crescimbeni, Gabriele Franciolini +3
We investigate the differences between several proposed formation scenarios for binary black holes (BBHs), including isolated stellar evolution, dynamical assembly in dense cluster…
Accuracy of ringdown models calibrated to numerical relativity simulations
Francesco Crescimbeni, Gregorio Carullo, Emanuele Berti +3
The ''ringdown'' stage of gravitational-wave signals from binary black hole mergers, mainly consisting of a superposition of quasinormal modes emitted by the merger remnant, is a k…
Can we identify primordial black holes? The role of subsolar gravitational wave events
Francesco Crescimbeni
The detection of a subsolar object in a compact binary merger is regarded as one of the most compelling signatures of a population of primordial black holes (PBHs). We critically e…
Theory-agnostic searches of non-gravitational modes in the ringdown
Francesco Crescimbeni
We present a theory-agnostic framework to search for extra-fundamental modes in the ringdown phase of black hole mergers. These modes, distinct from standard General Relativity (GR…
Taming systematics in distance and inclination measurements with gravitational waves: role of the detector network and higher-order modes
Adriano Frattale Mascioli, Francesco Crescimbeni, Costantino Pacilio +2
Gravitational-wave (GW) observations of compact binaries have the potential to unlock several remarkable applications in astrophysics, cosmology, and nuclear physics through accura…
The Irrelevance of Primordial Black Hole Clustering in the LVK mass range
F. Crescimbeni, V. Desjacques, G. Franciolini +6
We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…
