FLUMEN: Neural Emulator of an Advanced Stochastic Weak Lensing Model

Galymzhan Baltabay, Ville Vaskonen

Weak gravitational lensing by intervening structure magnifies distant sources and induces scatter in their luminosity distances. We develop an improved stochastic model for the dis…

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…

Technical Proposal for the Atom Interferometer CERN Experiment (AICE) Facility

Gianluigi Arduini, Nadja Augst, Mark G. Bason +79

We present the technical proposal for the Atom Interferometer CERN Experiment (AICE), a m vertical atom interferometer to be installed against the wall of the PX…

Axion Misalignment Across First-Order Phase Transitions

Galymzhan Baltabay, Francesco D'Eramo, Ville Vaskonen

When the axion mass is generated during a first-order phase transition and becomes non-vanishing only inside expanding true-vacuum bubbles, the standard picture of misalignment pro…

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…

JWST Constraints on Primordial Magnetic Fields

Malcolm Fairbairn, María Olalla Olea-Romacho, Juan Urrutia +1

Primordial magnetic fields (PMFs) enhance small-scale structure formation through the Lorentz force acting on baryons, boosting the abundance of low-mass halos and their hosted gal…
