Bayesian inference on Calabi--Yau moduli spaces and the axiverse: experimental data meets string theory
Mudit Jain, Elijah Sheridan, David J. E. Marsh +3
We develop tools of Bayesian inference on the moduli space of Calabi--Yau (CY) manifolds. We sample from the invariant Weil--Petersson (WP) measure using Markov Chain Monte Carlo a…
High-redshift, small-scale tests of ultralight axion dark matter using Hubble and Webb galaxy UV luminosities
Harrison Winch, Keir K. Rogers, Renée Hložek +1
We calculate the abundance of UV-bright galaxies in the presence of ultralight axion (ULA) dark matter (DM), finding that axions suppress their formation with a non-trivial depende…
Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions
Tibor Dome, Simon May, Alex Laguë +5
We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axi…
Interference in Fuzzy Dark Matter Filaments: Idealised Models and Statistics
Tim Zimmermann, David J. E. Marsh, Keir K. Rogers +2
Fuzzy (wave) dark matter (FDM), the dynamical model underlying an ultralight bosonic dark matter species, produces a rich set of non-gravitational signatures that distinguishes it…
Fuzzy Axions and Associated Relics
Elijah Sheridan, Federico Carta, Naomi Gendler +6
We study fuzzy axion dark matter in type IIB string theory, for axions descending from the Ramond-Ramond four-form in compactifications on orientifolds of Calabi-Yau hypersurfaces.…
