Analyzing gamma rays is an important aspect of modern astronomy and astrophysics, for they are the most powerful bands of energy on the electromagnetic spectrum. Comprehending gamma rays allows for deeper understanding of countless phenomena within our universe, such as cosmic rays. Cosmic rays are high energy particles thought to be formed via extremely violent explosions within our universe. These accelerated particles mirror conditions present in a supernova. A supernova is what occurs when a star at least 8 times as massive as our sun reaches the end of its lifespan and bursts. These explosions are the most powerful events ever to be recorded by astronomers and can be used to assist our understanding of cosmic rays in many ways. Using the Fermi Large Area Telescope (LAT), we observed the supernova remnant (SNR) G330.2+1.0. Previous X-ray observations could only characterize the spectra of a few regions within the SNR. In this project we compared previous X-ray data with the most current gamma-ray data from Fermi at GeV energy levels. While the SNR itself is not detected by Fermi, we placed the upper limits on the maximum GeV emission coming from this SNR. Our results help to discriminate between previously published models of the particle acceleration that has occurred in this SNR.

    This project is so full of cool stuff — and all explained in ways accessible to the non-specialist. Well done!
