Abstract
From the point of view of cosmology, the defining property of keV mass sterile neutrinos is that they behave as warm dark matter (WDM). In contrast to CDM, warm particles are kinematically energetic at early times and thus free stream out of small-scale primordial perturbations, inducing a cut-off in the power spectrum of density fluctuations. On large scales unaffected by the free streaming cut-off, structure formation is very similar in CDM and sterile neutrino cosmologies (and in WDM in general), but on scales comparable to or smaller than the cut-off, structure formation proceeds in a fundamentally different way in the two cases. No haloes form below a certain mass scale determined by the cut-off and the formation of small haloes above the cut-off is delayed (see Colín et al. 2000, Bode et al. 2001, Avila-Reese et al. 2001, Viel et al. 2005, Lovell et al. 2012, Schneider et al. 2012, Bose et al. 2016a, 2017).

The content of this chapter is based on the article Bose et al. ‘Reionization in sterile neutrino cosmologies’, Monthly Notices of the Royal Astronomical Society, Volume 463, Issue 4, p. 3848–3859, published 21 December 2016.

We note that our results in this section contradict those by Rudakovskyi and Iakubovskyi (2016), who find that in the 7 keV \(L_6=10\) model the Universe is reionised earlier than in CDM. This is ascribed to the lack of ‘mini’-haloes in the sterile neutrino cosmology, which reduces the average number of recombinations per hydrogen atom. In our analysis this amounts to a reduction in the value of \(N_\mathrm{{rec}}\) in Eq. 4.3.7. However, we have checked that even reducing the value of \(N_\mathrm{{rec}}\) by a factor of 10 does not affect our results significantly.
