We present recent results from the XENON1T experiment. Using a 0.65 t yr exposure, we perform one of the most sensitive searches for solar axions, an enhanced neutrino magnetic moment using solar neutrinos, and bosonic dark matter. We observe an excess of low-energy (1—7 keV) events. A solar axion signal is favoured at 3.4σ over background. The signal can also be explained by the beta-decay of tritium within the detector or by an enhanced neutrino magnetic moment. We review the XENON1T detector and its other results and present the evidence for excess low-energy events together with the alternative interpretations.
