abstract
We investigate an extension of the Minimal Standard Model by right-handed neutrinos (the $\nu$MSM) to incorporate neutrino masses consistent with oscillation experiments. Within this theory, the only candidates for dark matter particles are sterile right-handed neutrinos with masses of a few keV. Requiring that these neutrinos explain entirely the (warm) dark matter, we find that their number is at least three. We show that, in the minimal choice of three sterile neutrinos, the mass of the lightest active neutrino is smaller than ${\cal O}(10^{-5})$ eV, which excludes the degenerate mass spectra of three active neutrinos and fixes the absolute mass scale of the other two active neutrinos.

Resonant thermal lepton-flavour coherences at two loops enable dominant low-scale leptogenesis for both Dirac and Majorana singlet neutrinos down to GeV masses without mass degeneracy.
Tera-Z factories can produce millions of heavy neutral leptons and billions of axion-like particles under optimistic assumptions, turning them into exotics factories for discovery and detailed study.
Future MeV telescopes are projected to improve existing limits on sterile neutrino dark matter decay rates by several orders of magnitude.
Thesis summarizing an upper limit of 0.12 eV on the neutrino mass sum, bias calibration via CMB lensing cross-correlations, and tighter limits plus stronger normal-ordering preference in non-phantom dynamical dark energy models.
Z4-symmetric Type I seesaw fits neutrino data with minimal parameters and enables freeze-in dark matter plus resonant leptogenesis via soft symmetry breaking.
