Cosmic rays have baffled astronomers for over a century, as all potential origins have yet to be determined. Most of these galactic accelerated atomic nuclei are thought to be created in two possible fashions: from a supernova, or within a massive star cluster (MSC). In this study, we analyzed gamma-ray emission coincident with two MSCs named G25 and G27. Using NASA’s Fermi Large Area Telescope (LAT), we confirmed that the sources of gamma rays are spatially extended and emit up to the maximum energies observed by the LAT. So far, only the closest MSC to Earth …

The neutral subatomic neutrinos are astronomical messengers that can provide us information to investigate the most violent astrophysical sources: supernovas, gamma-ray bursts, and cataclysmic phenomena involving black holes and neutron stars. As these astrophysical neutrinos freely travel from their point of origin without being scattered by interstellar magnetic fields, we can analyze these particles by observing cosmic-ray air showers on the Earth’s atmosphere. These are produced by the energetic neutrinos by interacting with the air particles that produce a wavefront of Cherenkov radiation. To better identify these background neutrinos, IceCube, the South Pole Neutrino Observatory, constructed an imaging air Cherenkov …

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 …
