The existence of additional neutrino flavors (so-called sterile neutrinos) with masses at the eV scale were suggested by a set of experimental data, which cannot be explained within the three-flavor framework. These anomalies mainly come from short baseline neutrino oscillation experiments, reactor experiments and radioactive source experiments. Recently the MiniBooNe collaboration published new results about the observation of an excess of electron neutrino in the muon neutrino flux, confirming, at higher statistical level, the previous measurement reported by the Liquid Scintillator Neutrino Detector (LSND) experiment.

In this talk I will explain the latest MiniBooNe results together  with the other experimental hints and I will show how, in the framework of the global analysis, the space of the sterile neutrino oscillation parameters can be constrained by the experimental data.
