Description
Recent observations in the ultrahigh-energy (UHE) gamma-ray band have revealed an abundance of source populations in our Galaxy that operate as efficient particle accelerators. These sources include microquasars, pulsar wind nebulae, young star clusters, and supernova remnants. Although not yet fully understood, the spectra, morphologies, and temporal variabilities of these sources carry important clues to the origin of PeV cosmic rays and shed light on the properties of the underlying particle accelerators. This talk will review our current understanding of these UHE sources and identify the key theoretical challenges.
