Description
The past decade and a half have seen the commissioning of four new ground based gamma-ray observatories (VERITAS, HESS, MAGIC, and HAWC) that have fundamentally changed our view of the gamma-ray sky above 100 GeV. It has also seen the launch of the Fermi Gamma-ray Space Telescope, which dramatically altered our view of the gamma-ray universe between 30 MeV and 300 GeV and is gathering an increasing number of detections out to 1 TeV. Together these instruments have revealed new classes of gamma-ray sources, shed light on long-standing mysteries, and forced us to revise or abandon long-held assumptions. Some of the most recent advances from this watershed period in gamma-ray astronomy will be reviewed, primarily in the context of galactic and extragalactic cosmic rays. Special attention will be paid to the interplay with cosmic ray and neutrino observatories, as well as to new approaches for exploiting the rich synergy between the three US observatories—VERITAS, Fermi, and HAWC—currently in simultaneous operation and providing unprecedented gamma-ray coverage of the northern sky between 30 MeV and 100 TeV.
