The gamma radiation spawn by cosmic rays along their interstellar journey has received much attention over the years as an efficient means to trace the evolution of the cosmic-ray flux and spectrum on kiloparsec scales across the Milky Way.
The data are interpreted in the framework of an elementary scenario which involves cosmic-ray production by diffusive shock acceleration in supernova...

SNRs are commonly believed to be the accelerators of the galactic cosmic rays -- mainly protons -- and are expected to produce $\gamma$-rays through the inelastic proton-proton collisions. Fermi/LAT was expected to detect many of those, but only a dozen is listed in the most up to date Fermi/LAT 2nd Source catalogue. To test whether the observed number of SNRs is in agreement with the...

The H.E.S.S. Galactic Plane Survey was an ambitious observational program which spanned a period of over 10 years, finishing just recently in 2013. The rich data set accumulated covers nearly the entire Galactic plane visible from Namibia; has an unprecedented, deep sensitivity; and features an energy coverage and angular resolution which is well suited for the search for sources of Galactic...

Massive star-forming regions assemble a large number of young stars with remnants of stellar evolution and a very dense environment. Therefore, particles accelerated in supernova remnants and pulsar wind nebulae encounter optimal conditions for interacting with target material and photon fields, and thus produce gamma-ray emission. However, observations are challenging because multiple...

The High-Altitude Water Cherenkov (HAWC) TeV Gamma-Ray Observatory located at a site about two hours' drive east of Puebla, Mexico on the Sierra Negra plateau (4100 m a.s.l.) will be inaugurated in March 2015. The array of 250 water Cherenkov detectors can observe large portions of the sky simultaneously and, with an energy range of 100 GeV to 100 TeV, is currently one of the most sensitive...

The Cygnus-X star-forming region ("Cygnus") is the richest star-forming region within 2 kpc of Earth and is home to a wealth of potential cosmic ray accelerators, including supernova remnants, massive star clusters, and pulsar wind nebulae. Over the past five years, discoveries by several gamma-ray observatories sensitive in different energy bands, including the identification by Fermi-LAT of...
