dc.description.abstractWe analyze the recently released CoGeNT data with a focus on their time-dependent properties. Using a variety of statistical tests, we confirm the presence of modulation in the data, and find a significant component at high (Eee * 1:5 keVee) energies. We find that standard elastic WIMPs in a Maxwellian halo do not provide a good description of the modulation. We consider the possibility of nonstandard halos, using halo-independent techniques, and find a good agreement with the DAMA modulation for QNa 0:3, but disfavoring interpretations with QNa ¼ 0:5. The same techniques indicate that CDMS-Ge should see an Oð1Þ modulation, and XENON100 should have seen 10–30 events (based upon the modulation in the 1.5–3.1 keVee range), unless Leff is smaller than recent measurements. Models such as inelastic dark matter provide a good fit to the modulation, but not the spectrum. We note that tensions with XENON could be alleviated in such models if the peak is dominantly in April, when XENON data are not available due to noise.en_US
