Searching for the high-energy neutrino counterpart signals: The case of the Fermi bubbles signal and of dark matter annihilation in the inner Galaxy

The recent uncovering of the Fermi bubbles/haze in the Fermi gamma-ray data has generated theoretical work to explain such a signal of hard gamma rays in combination with the WMAP haze signal. Many of these theoretical models can have distinctively different implications with regards to the production of high-energy neutrinos. We discuss the neutrino signals from different models proposed for the explanation of the Fermi bubbles/haze, more explicitly, from dark matter annihilation in the galactic halo with conditions of preferential cosmic ray diffusion, from recent active galactic nucleus jet activity, from periodic diffusive shock acceleration, from stochastic second order Fermi acceleration and from long time-scale star formation in the galactic center in combination with strong galactic winds. We find that some of these models will be probed by the IceCube DeepCore detector. Moreover, with a km(3) telescope located in the Northern Hemisphere, we will be able to discriminate between the hadronic, leptonic and the dark matter models. Additionally using the reconstructed neutrino spectra we will probe annihilation of TeV scale dark matter towards the galactic center.
