Description
A recent analysis of the Fermi data provides evidence of the emission of high energy
gamma rays (up to 100 GeV) with a high-intensity E-2 spectrum. This emission was
detected as originating from two large areas around the Galactic center, spanning
50° above and below the Galactic center and 40° in longitude, with no evidence of
spacial variation both in the spectrum shape and in the intensity. Currently, not all
observed features of the Fermi bubbles are fully explained by a leptonic mechanism
and an hadronic mechanism has been proposed. The possible origin of high energy
gammas from an hadronic mechanism makes these bubbles promising sources for
high energy neutrino emission.
The KM3NeT collaboration has started the implementation of the first phase of a
deep-sea research infrastructure hosting a multi-cubic-kilometer scale high energy
neutrino detector in the Mediterranean Sea. The Galactic Centre and its environment
will be in the central field of view of this detector, making it the ideal instrument for
the observation of neutrino from Fermi Bubbles.
In this work some predictions, based on Monte Carlo simulations and on the high
energy gamma observations, regarding the possible detection of high energy
neutrinos from the Fermi bubbles will be presented.
