Abstract

The project tests a theory suggesting dark matter may consist of supermassive particles from the early Universe. Their decay should ultimately result in a large so called super-preshowers of photons, widely distributed across both space (an area larger than the Earth) and time (reaching different parts of the Earth at different times).

CREDO make use of citizen scientist for their detection via a smartphone application. The app uses the camera to look for the bright pixels caused by the impact of a high-energy particle on the CCD detector in the camera. A small ‘thumbnail’ centred on this detection along with the time, date and localization it occurred is sent to the CREDO servers to be analyzed.
