The diffuse gamma radiation arising from the interaction of cosmic-ray particles with matter and radiation in the Galaxy is one of the few probes available to study the origin of the cosmic rays. Data from the Milagro gamma-ray observatory—a water Cerenkov detector that continuously views ~2 sr of the overhead sky—shows that the brightest extended region in the entire northern sky is the Cygnus region of the Galactic plane. The TeV image of the Cygnus region contains at least one new source…

High energy gamma rays can provide fundamental clues to the origins of cosmic rays. In this thesis, TeV gamma-ray emission from the Cygnus region is studied. Previously the Milagro experiment

A Measurement of the Spatial Distribution of Diffuse TeV Gamma-Ray Emission from the Galactic Plane with Milagro

Diffuse γ-ray emission produced by the interaction of cosmic-ray particles with matter and radiation in the Galaxy can be used to probe the distribution of cosmic rays and their sources in different

The Cygnus Region - a prime target for cosmic ray accelerators

Regions with prominent star formation activity are of great interest for understanding the properties of cosmic rays. The interactions of cosmic rays with the Galactic interstellar gas and radiation

The Cosmic-Ray and Gas Content of the Cygnus Region as Measured in Gamma Rays by the Fermi Large Area Telescope

The Cygnus region hosts a giant molecular-cloud complex which actively forms massive stars. Interactions of cosmic rays with interstellar gas and radiation fields make it shine at gamma-ray energies.


Recently the Milagro experiment observed diffuse multi-TeV gamma ray emission in the Cygnus region, which is significantly stronger than what is predicted by the Galactic cosmic ray model. However,

Neutrinos from cosmic ray accelerators in the Cygnus region of the galaxy

While supernova remnants have been identified as the most likely sources of the galactic cosmic rays, no conclusive observational evidence for this association exists. We show here that IceCube has

Cosmic-Ray Origins

Observations with NASA's Fermi Large Area Telescope are reported that are directly related to the origin of cosmic rays, and distributed emission of gamma-rays over the energy range of 1 to 100 GeV in the Cygnus X region of the sky with a “cocoon” of freshly accelerated cosmic rays is identified.



Cosmic-ray electrons and the diffuse gamma-ray spectrum

The bulk of the diffuse galactic gamma-ray emission above a few tens of GeV has been conventionally ascribed to the decay of neutral pions produced in cosmic-ray interactions with interstellar

Discovery of very-high-energy γ-rays from the Galactic Centre ridge

The source of Galactic cosmic rays (with energies up to 1015 eV) remains unclear, although it is widely believed that they originate in the shock waves of expanding supernova remnants. At present the

Detection of TeV Gamma‐Ray Emission from the Cygnus Region of the Galaxy with Milagro Using a New Background Rejection Technique

Milagro is a TeV gamma‐ray observatory that utilizes a large water Cherenkov detector to observe extensive air showers (EAS) produced by high energy particles impacting the Earth’s atmosphere.

Evidence for TeV gamma-ray emission from a region of the galactic plane.

Evidence for a TeV gamma-ray signal from a region of the galactic plane by Milagro, a large-field-of-view water Cherenkov detector for extensive air showers, is reported, consistent with an extrapolation of the EGRET spectrum between 1 and 30 GeV in this galactic region.
