COSINE-100 is a direct dark matter detection experiment that aims to test DAMA/LIBRA’s claim of dark matter discovery using 106 kg of low-background NaI(Tl) detectors submerged in a 2-tonne liquid scintillator veto. The physics run of the experiment began in September 2016, and a 3.5 count/kg/day/keV background level within the 2-6 keV region of interest has been achieved. Several physics analyses, including WIMP searches and an annual modulation search, have been performed using a 2 keV energy threshold. Recently, this threshold has been lowered to 1 keV. In this talk, we describe the method used to lower the threshold to 1 keV and recent results with this lowered threshold.
