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…
Extreme Axions Unveiled: a Novel Fluid Approach for Cosmological Modeling
Harrison Winch, Renee Hlozek, David J. E. Marsh +2
Axion-like particles (ALPs) are a well-motivated dark matter candidate that solve some of the problems in the clustering of large scale structure in cosmology. ALPs are often descr…
