Two emission mechanisms in the Fermi Bubbles: A possible signal of annihilating dark matter

Slatyer, Tracy R.; Hooper, Dan

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 latitude, and is consistent with arising from inverse Compton scattering of the interstellar radiation field by cosmic-ray electrons with an approximately power-law spe…

Planck and the local Universe: Quantifying the tension

Verde, Licia; Jimenez, Raul; Protopapas, Pavlos

We use the latest Planck constraints, and in particular constraints on the derived parameters (Hubble constant and age of the Universe) for the local universe and compare them with local measurements of the same quantities. We propose a way to quantify whether cosmological parameters constraints from two different experiments are in tension or not…
