The Hunt for PeVatrons
Figure 1: An image of the supernova remnant Cassiopeia A from NASA’s Chandra X-ray Observatory. [NASA/CXC/SAO]What are our galaxy’s most energetic and extreme particle accelerators? Could it be supernova remnants, the remains of the violent death of a massive star? Or might it be the nebulae that form around pulsars, rapidly rotating and highly magnetized neutron stars? Perhaps surprisingly, this is still an open question in high-energy astrophysics and the list of possible suspects is much larger than just those mentioned above.
However, we know that these particle accelerators exist. We know this because we are constantly being bombarded by high-energy cosmic rays — protons or heavier atomic ...
