Modelling frequency-dependent tidal deformability for environmental black-hole mergers
Valerio De Luca, Andrea Maselli, Paolo Pani
Motivated by events in which black holes can lose their environment due to tidal interactions in a binary system, we develop a waveform model in which the tidal deformability inter…
Implications of the Weak Gravity Conjecture for Tidal Love Numbers of Black Holes
Valerio De Luca, Justin Khoury, Sam S. C. Wong
The Weak Gravity Conjecture indicates that extremal black holes in the low energy effective field theory should be able to decay. This criterion gives rise to non-trivial constrain…
Heavy primordial black holes from strongly clustered light black holes
Valerio De Luca, Gabriele Franciolini, Antonio Riotto
We show that heavy primordial black holes may originate from much lighter ones if the latter are strongly clustered at the time of their formation. While this population is subject…
Ruling out Initially Clustered Primordial Black Holes as Dark Matter
V. De Luca, G. Franciolini, A. Riotto +1
Combining constraints from microlensing and Lyman- forest, we provide a simple argument to show that large spatial clustering of stellar-mass primordial black holes at the time…
Signals from the Early Universe: Black Holes, Gravitational Waves and Particle Physics
Valerio De Luca
We dedicate this thesis to the study of signatures coming from the primordial epochs of the universe. We will focus in particular on Primordial Black Holes (PBHs), which may be for…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
On the Cosmological Stability of the Higgs Instability
Valerio De Luca, Alex Kehagias, Antonio Riotto
The Standard Model Higgs potential becomes unstable at large Higgs field values where its quartic coupling becomes negative. While the tunneling lifetime of our current electroweak…
Probing Anisotropies of the Stochastic Gravitational Wave Background with LISA
Nicola Bartolo, Daniele Bertacca, Robert Caldwell +19
We investigate the sensitivity of the Laser Interferometer Space Antenna (LISA) to the anisotropies of the Stochastic Gravitational Wave Background (SGWB). We first discuss the mai…
A Note on the Abundance of Primordial Black Holes: Use and Misuse of the Metric Curvature Perturbation
V. De Luca, A. Riotto
The formation of Primordial Black Holes (PBHs) through the collapse of large fluctuations in the early universe is a rare event. This manifests itself, for instance, through the no…
