The structure of the Earth's interior, and in particular of the the Earth's core, is still a big puzzle. Global informations about the Earth (such as its mass and its moment of inertia) can be extracted from gravitational measuremnts. Propagation of seismic waves allow us to infer properties of the crust, the mantle and the outer core. The inner core, however, cannot be tested directly, as seismic waves cannot cross the liquid outer core. Neutrinos can be used to measure the Earth's density profile by means of electroweak interactions only, thus giving an independent and complementary picture of the Earth.
I will show the first sensitive neutrino Earth tomography result to date using one year of IceCube atmospheric neutrinos data.
