Primordial black holes and their gravitational-wave signatures
Eleni Bagui, Sebastien Clesse, Valerio De Luca +17
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain…
Gravitational Waves in the Circular Restricted Three Body Problem
Mikel Martin Barandiaran, Sachiko Kuroyanagi, Savvas Nesseris
The prospect of unprecedented high-quality data of gravitational waves in the upcoming decades demands a theoretical effort to optimally study and analyze the signals that next gen…
Log-periodic gravitational-wave background beyond Einstein gravity
Gianluca Calcagni, Sachiko Kuroyanagi
Periodic patterns of logarithmic oscillations can arise in primordial curvature perturbation spectra and in the associated gravitational-wave background via different mechanisms. W…
Effects of orbital precession on hyperbolic encounters
Marienza Caldarola, Sachiko Kuroyanagi, Savvas Nesseris +1
The hyperbolic encounters of two massive objects are characterized by the emission of a gravitational wave burst, with most of the energy released during the closest approach (near…
Non-Linearity-Free prediction of the growth-rate using Convolutional Neural Networks
Koya Murakami, Indira Ocampo, Savvas Nesseris +2
The growth-rate of the large-scale structure of the Universe is an important dynamic probe of gravity that can be used to test for deviations from General Relativity. How…
Stochastic gravitational wave background constraints from Gaia DR3 astrometry
Santiago Jaraba, Juan García-Bellido, Sachiko Kuroyanagi +2
Astrometric surveys can be used to constrain the stochastic gravitational wave background (SGWB) at very low frequencies. We use proper motion data provided by Gaia DR3 to fit a ge…
