Signatures of Dark Matter halos in LISA via Stochastic Diffraction
Han Gil Choi, Juan Urrutia, Miguel Zumalacárregui
The paper investigates how wave‑optics lensing by many low‑mass dark‑matter halos along the line of sight can produce stochastic diffraction signatures in LISA gravitational‑wave s…
JWST Constraints on Primordial Magnetic Fields
Malcolm Fairbairn, MarÃa 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…
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…
Constraints on Dark Matter Models from Supermassive Black Hole Evolution
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
A semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) within the CDM paradigm has been shown to yield stellar mass-BH mass relations that r…
Starlight from JWST: Implications for star formation and dark matter models
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We confront the star formation rate in different dark matter (DM) models with UV luminosity data from JWST up to and legacy data from HST. We find that a transition fro…
Quintessence and phantoms in light of DESI 2025
Ioannis D. Gialamas, Gert Hütsi, Martti Raidal +3
We analyse DESI BAO, CMB, and supernova data to explore the physical origin of the DESI indication for dynamical dark energy. Beyond the standard CPL parametrization, we explore tr…
