Search for the Anomalous Events Detected by ANITA Using the Pierre Auger Observatory – publication
27 maart 2025
Several years ago, a cosmic particle detector in Antarctica observed a series of unusual radio signals, according to an international research group that includes scientists from Penn State.
The strange radio pulses were detected between 2016 and 2018 by NASA’s Antarctic Impulsive Transient Antenna (ANITA), a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere, and a new study provides additional context to the nearly decade-old results. The goal of the ANITA experiment was to gain insight into distant cosmic events by analyzing signals that reach the Earth. Rather than reflecting off the ice, the signals — a form of radio waves — appeared to be coming from below the horizon, an orientation that could not be explained by the current understanding of particle physics and may have hinted at new types of particles or interactions previously unknown to science, the team said at the time. A new study using the Pierre Auger Observatory in Argentina analyzed 15 years of cosmic data to try to make sense of those signals. The team of international scientists, including Penn State researchers, published their results in the journal Physical Review Letters.
