Giant Structure in our Galaxy

NASA's Fermi Telescope Finds Giant Structure in our Galaxy

[1005.5480] Giant Gamma-ray Bubbles from Fermi-LAT: AGN Activity or Bipolar Galactic Wind?
http://arxiv.org/abs/1005.5480

The bubbles display a spectrum with higher peak energies than the diffuse gamma-ray glow seen throughout the sky. In addition, the bubbles display sharp edges in Fermi LAT data.
Both of these qualities suggest that the structure arose in a sudden, impulsive event.

From end to end, the newly discovered gamma-ray bubbles extend 50,000 light-years, or roughly half of the Milky Way's diameter,



Electrons moving near the speed of light are an important source of the Milky Way's diffuse gamma-ray glow; they also power a new galactic structure uncovered in Fermi data. When a relativistic electron strikes a low-energy (radio or infrared) photon, the collision slightly slows the electron and ramps up the photon to gamma-ray energies. Credit: NASA Goddard
