[HTML][HTML] Two emission mechanisms in the Fermi bubbles: a possible signal of annihilating dark matter
D Hooper, TR Slatyer - Physics of the Dark Universe, 2013 - Elsevier
We study the variation of the spectrum of the Fermi Bubbles with Galactic latitude. Far from
the Galactic plane (| b|≳ 30°), the observed gamma-ray emission is nearly invariant with …
