DESCRIPTION:I discuss the signatures left by massive neutrinos on the spat
 ial distribution of neutral hydrogen (HI) in the post-reionization era by 
 running hydrodynamic simulations that include massive neutrinos as additio
 nal collisionless particles. Our results show that HI is more strongly clu
 stered in cosmologies with massive neutrinos\, while its abundance\, \nΩH
 I(z)\, is lower. These effects arise mainly from the impact of massive neu
 trinos on cosmology: they suppress both the amplitude of the matter power 
 spectrum on small scales and the abundance of dark matter halos. Modelling
  the HI distribution with hydrodynamic simulations at z>3\, and a simple a
 nalytic model at z\n\nhttps://indico.ific.uv.es/event/2657/
