I will review one of the predictions of the Big Bang theory, the existence of a cosmic neutrino background. I will then present the effect that neutrino masses induce on cosmological observables at linear order. I will show the canonical effect that has been commonly employed on cosmology to weigh neutrinos: their effect on the power spectrum. I will show why we need to consider other...
A review of the physical effects and impacts of several dark matter particle candidates on the observable characteristics of 21-cm emission and absorption from the high-redshift Universe will be presented, including annilation to gamma-rays, energy release from black holes, elastic scattering
with baryons, and dark matter free-streaming effects.
