Description
The 21cm radiation from cosmic neutral hydrogen can be used to survey large cosmological volumes of the Universe through intensity mapping. I will discuss the impact of neutrino masses on the abundance and clustering of neutral hydrogen, that we have investigated through hydrodynamic simulations with massive neutrinos. I will show that it can be understood by accounting for the effects neutrinos induce on the properties of matter and halos. I will show forecasts on how well upcoming instruments, like the Square Kilometer Array, can detect the minimum mass of the neutrino masses.
