Assessing the Impact of Instrumental Requirements on the Scientific Performance of the Einstein Telescope
Ulyana Dupletsa, Francesco Iacovelli, Mikhail Korobko +23
The paper evaluates how different design choices and noise characteristics of the Einstein Telescope affect its ability to detect and analyze various gravitational‑wave sources, us…
Novel ringdown tests of general relativity with black hole greybody factors
Romeo Felice Rosato, Francesco Crescimbeni, Sophia Yi +2
We present GreyRing, a new model for the post-merger signal in black-hole binary coalescences based on the greybody factor of the remnant. The model accurately reproduces the full…
Black Hole Ringdown Amplitudescopy
Francesco Crescimbeni, Xisco Jimenez-Forteza, Paolo Pani
Black hole ringdowns in extensions of General Relativity (GR) generically exhibit two distinct signatures: (1) theory-dependent shifts in the standard black-hole quasinormal modes,…
Theory-agnostic searches for non-gravitational modes in black hole ringdown
Francesco Crescimbeni, Xisco Jimenez Forteza, Swetha Bhagwat +2
In any extension of General Relativity (GR), extra fundamental degrees of freedom couple to gravity. Besides deforming GR forecasts in a theory-dependent way, this coupling generic…
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…
