Description
High PeV to EeV cosmic rays can be used to probe extreme environments in the universe like supernovae and AGN. When these cosmic rays hit the Earth's atmosphere they generate large cascades of secondary particles called "airshowers". The evolution of these airshowers is still not completely understood, with current efforts to resolve it focusing on beamforming with radio arrays like LOFAR. However, simulations run using CoREAS show that the frequency range unlocked by SKA-low can provide more insight through interference patterns. These mainly show up inside the Cherenkov cone at frequencies between 100 and 400 MHz, frequencies that match great with those observable by the SKA-low array. The simulations currently point at strong correlation between the frequency of interference and the slant distance between the shower maximum and ground intersection.
