Astro Seminar: "Massive Neutrinos and Large-scale Structure: Forecasts for SKA"

In the first part of the seminar I will discuss some of the effects that massive neutrinos induce on the large-scale structure of the Universe, from their impact on the clustering of halos, galaxies and voids to their signatures on the BAO. In the second part of the seminar I will discuss the possibility of using the hydrogen 21cm line to study cosmology. I will show how well the future SKA1-MID instrument will be able to constraint the sum of the neutrino masses and the accuracy with which the position of the BAO can be measured when accounting for the instrument setup and presence of foregrounds.
