Description
We present the first full-sky analysis of the cosmic ray arrival direction distribution with data collected by the High-Altitude Water Cherenkov and IceCube observatories in the northern and southern hemispheres at the same median primary particle energy of 10 TeV. The combined sky map and angular power spectrum largely eliminate biases that result from partial sky coverage and present a key to probe into the propagation properties of TeV cosmic rays through our local interstellar medium and the interaction between the interstellar and heliospheric magnetic fields. From the map, we determine the horizontal dipole components of the anisotropy δ0h= 9.16× 10− 4 and δ6h= 7.25× 10− 4(±0.04× 10− 4). In addition, we infer the direction (229. 2±3. 5 RA, 11. 4±3. 0 decl.) of the interstellar magnetic field from the boundary between large-scale excess and deficit regions from which we estimate the missing …
