WarmAndFuzzy: the halo model beyond CDM

Understand

Cold dark matter (CDM) is a well established paradigm to describe cosmological structure formation, and works extraordinarily well on large, linear, scales.

• Progressing further in dark matter physics requires being able to understand structure formation in the non-linear regime, both for CDM and its alternatives.
• This short note describes a calculation, and accompanying code, WarmAndFuzzy, incorporating the popular models of warm and fuzzy dark matter (WDM and FDM) into the standard halo model to compute the non-linear matter power spectrum.
• The FDM halo model power spectrum has not been computed before.
