Join us on Thursday, February 13th for another installment of our 2025 Winter Colloquia Series! Guest lecturer, Dr. Agnieszka Leszczynska, will be visiting from the University of Delaware and will present her talk "Fantastic Cosmic Rays & How to Find Them".

Abstract:

Over the past decades, scientists have measured cosmic rays with various instruments and techniques over an impressive range of energies, from GeV to hundreds of EeV. Features of their energy, mass, as well as arrival direction distributions can be used to infer information about their possible acceleration sites. High-energy cosmic rays can initiate large particle cascades upon entering Earth's atmosphere. These, so called extensive air showers can be detected on the ground with large arrays of detectors or specialized telescopes. Air-shower measurements, in addition to advancing our knowledge of cosmic rays, teach us about particle physics at energies unreachable by human-made accelerators. In this talk I will present an overview of indirect cosmic-ray measurements with a focus on the results from IceCube, which can be used as a unique air-shower detector.
