Halo mass functions in mixed cold and fuzzy dark matter models
Sarah C. Johnston, Simon May, Tibor Dome +5
We investigate the impact of mixed cold and fuzzy dark matter (MDM) cosmologies on the halo mass function (HMF) using numerical simulations performed with the AxiREPO framework. We…

The Impact of Fuzzy Dark Matter Dynamics on the Accumulation and Fragmentation of Primordial Gas
Alexander Tocher, Anastasia Fialkov, Simon May +4
Fuzzy Dark Matter (FDM), particularly in the eV mass regime is frequently used to characterize wave-like interference effects. It exhibits macroscopic wave properties, w…

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…
