Description

The Karlsruhe Tritium Neutrino (KATRIN) experiment probes the effective electron anti-neutrino mass by precisely measuring the tritium beta-decay spectrum close to its kinematic endpoint. A world-leading upper limit of $0.45\,\mathrm{eV/c}^2$ ($90\%$ C.L.) has been set with the first five measurement campaigns.
The same data can be used to search for sterile neutrinos with masses on the eV scale. The results exclude large parts of anomalies observed in short-baseline oscillation experiments.
This talk features the latest KATRIN neutrino mass and sterile neutrino results. Additionally, an overview of the next KATRIN measurement phase with an updated detector, allowing to search for sterile neutrinos on the keV scale, is given.
