Gamma Rays and Ghost Particles: Investigating IceCube Alerts with HAWC
Published: March 4, 2026
Duration: 19:26
In this episode, we dive into the cutting-edge realm of multi-messenger astronomy to explore how scientists are attempting to link high-energy neutrinos with gamma-ray emissions to uncover the origins of ultra-high-energy cosmic rays. We discuss a recent study by the HAWC collaboration, which cross-referenced 368 public astrophysical neutrino alerts from the IceCube observatory with archival gamma-ray data from the HAWC observatory in Mexico.
We break down the unique capabilities of both observatories and how researchers utilized a Bayesian Block algorithm to search for spatial and temporal coincidences (flares) between the two datasets. Tune in to...
