Description
The MicroBooNE collaboration recently released a series of measurements aimed at investigating the nature of the excess of low-energy electromagnetic shower events observed by the MiniBooNE collaboration. In this talk, we will present the latest results from both a search of single photons in MicroBooNE, as well as a series of three independent analyses leveraging different reconstruction paradigms which look for an anomalous excess of electron neutrino events. We additionally will highlight new results that use these well-understood selections to perform a search for an eV scale sterile neutrino in the 3+1 oscillation framework. Constraints are presented for regions of sterile neutrino oscillation parameter space relevant to the Gallium/Reactor $\nu_e$ disappearance anomaly and LSND/MiniBooNE $\nu_e$ appearance anomalies.
