Standard Model Higgs Peaks: a Note on the Vacuum Instability during Inflation

G. Franciolini, A. Kehagias, A. Riotto

In the Standard Model, the Higgs potential develops an instability at high field values when the quartic self-coupling runs negative. Large quantum fluctuations during cosmic infla…

Uncovering the population of compact binary mergers and their formation pathways with gravitational waves through the Einstein Telescope

M. Arca-Sedda, I. Dvorkin, G. Franciolini +19

Ground-based gravitational-wave (GW) observatories have transformed our view of compact-object mergers, yet their reach still limits a comprehensive reconstruction of the processes…

Nonlinear Gravity and Multipole Turbulence

A. Ianniccari, A. Kehagias, L. Lo Bianco +1

We derive a kinetic Boltzmann equation characterizing the long-term statistical behavior of the turbulent dynamics of nonlinear interacting gravitational wave multipoles in Minkows…

Non-vanishing non-linear Static Love Number of a Class of Extremal Reissner-Nordstrom Black Holes

L. R. Gounis, A. Kehagias, G. Panagopoulos +1

We compute the tidal Love numbers for a particular axially symmetric configuration of extremal Reissner-Nordstrom geometry. By exactly solving the non-linear Einstein equations, we…

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…

The Vanishing of the Non-linear Static Love Number of Kerr Black Holes and the Role of Symmetries

L. -R. Gounis, A. Kehagias, A. Riotto

We investigate the tidal response of Kerr black holes in four-dimensional space-times subjected to external gravitational fields. Using the Ernst formalism and Weyl coordinates, we…
