1/n We saw an excess of events in the energy region 1-7 keV in XENON1T data. There are 285 electronic recoil events observed, with 232+-15 expected from the background. Extensive checks allowed us to exclude backgrounds from known particles and systematic effects as the source pic.twitter.com/L6yYY3tKUI
