The Loud Tail of the Supermassive Black Hole Binary Population: Multimessenger Candidates and Prospects for SKAO
Juhan Raidal, Ville Vaskonen, Juan Urrutia +1
We assess whether electromagnetically identified supermassive black hole (SMBH) binary candidates populate the rare, high-amplitude tail of the gravitational wave (GW) amplitude di…
Memoirs of the curvaton: non-perturbative non-Gaussianity and supermassive primordial black holes
S. Allegrini, A. J. Iovino, G. Perna +1
The curvaton provides a simple mechanism for generating strongly non-Gaussian curvature perturbations after inflation, with potentially important consequences on small scales. We s…
Constraints on primordial black holes from the first part of LIGO-Virgo-KAGRA fourth observing run
M. Andrés-Carcasona, A. J. Iovino, E. Vallejo-Pagès +4
We analyse primordial black hole (PBH) populations using state-of-the-art modelling of PBH binaries, deriving the strongest bounds on PBH abundance in the - rang…
The Heavy Tailed Non-Gaussianity of the Supermassive Black Hole Gravitational Wave Background
Juhan Raidal, Juan Urrutia, Ville Vaskonen +1
We study the non-Gaussian features of the gravitational wave (GW) background generated by a population of inspiraling supermassive black hole (SMBH) binaries. We show that the SMBH…
A non-perturbative framework for N-point functions of locally non-Gaussian fields
Hardi Veermäe
We present a non-perturbative approach to correlation functions and polyspectra of locally non-Gaussian fields and develop a semi-perturbative framework that does not rely on a loc…
Primordial black holes: constraints, potential evidence and prospects
Bernard Carr, Antonio J. Iovino, Gabriele Perna +2
Primordial black holes (PBHs) may have formed in the early Universe and may account for all or part of the dark matter. In this review, we summarize the current observational const…
