Description
Recent multi-messenger observations of the Galactic plane have revealed new classes of gamma-ray emitters at energies reaching into the multi-tens of TeV range, challenging our previous understanding based on lower-energy data. These unexpected sources include TeV halos—extended gamma-ray emissions around isolated pulsars that cannot be explained as traditional pulsar wind nebulae—as well as X-ray binaries and supernova remnants exhibiting emissions up to 100 TeV. In this talk, we will present recent findings from studies utilizing data from HAWC, Fermi-LAT and IceCube. Furthermore, we will discuss theoretical interpretations that shed light on these observations and explore their implications for high-energy astrophysical processes.
