Exploring the Inner Structure of Ultra-High-Energy Air Showers with AugerPrime
Cosmic rays are high-energy particles arriving at Earth from outer space. When the most energetic of these particles hit the atmosphere, they create enormous cascades of secondary particles, known as air showers, that spread over many square kilometers. While scientists have learned a great deal about these showers, what happens at their very core—close to where the cascade is most intense—remains largely unknown.
In this project, we will explore this unexplored region using data from the Pierre Auger Observatory, the world’s largest cosmic-ray detector. We will focus on a particularly dense part of the detector array (SD-433) and take advantage of recent upgrades (AugerPrime), which include new sensors capable of measuring extremely large particle densities near the shower axis.
The student will work with real experimental data to study how particles are distributed at the center of these showers and compare the results with computer simulations. This project offers a unique opportunity to engage with cutting-edge research, learn data analysis techniques used in astroparticle physics, and contribute to our understanding of fundamental particle interactions at energies far beyond those accessible in human-made accelerators.
Requirements: This project is intended for undergraduate students in Physics with prior experience in programming (preferably C++ and/or Python). The internship is designed to be carried out in person in Lisbon.
