Collaborators from Fermi-LAT realized that the abundance of cosmic-ray protons in the LAT data set might enable them to measure cosmic-ray anisotropy, and so they conducted the first search for cosmic-ray proton anisotropy using Fermi-LAT data. They present their results in a paper published last week in The Astrophysical Journal.

It has been a week since the 36th International Cosmic Ray Conference ended in Madison, WI. Over the course of eight days of meetings, 815 participants from 39 countries gathered at Memorial Union at the University of Wisconsin–Madison. In total, the meeting yielded 1,056 papers, 406 oral talks, 650 posters, 35 plenary talks, two diversity events, a public lecture, and an art gallery.

The 36th International Cosmic Ray Conference (ICRC) kicks off tomorrow in Madison, WI. ICRC is a physics conference organized biennially by the Commission on Astroparticle Physics (C4) of the International Union of Pure and Applied Sciences (IUPAP) in which physicists from around the world present the results of their research in astroparticle physics.

In an attempt to better understand the anisotropy, the IceCube Neutrino Observatory and the HAWC gamma-ray observatory have united their efforts to study cosmic-ray arrival directions in both hemispheres at the same primary energy. The goal of this combined observation was to get a nearly full-sky coverage to study the propagation of cosmic rays with median energy of 10 TeV through our local interstellar medium as well as the interactions between interstellar and heliospheric magnetic fields. Results have just been accepted for publication in The Astrophysical Journal and include measurements on how the anisotropy modulations are distributed over different angular scales.

Since cosmic rays were discovered in 1912, scientists have sought the origins of these mysterious particles. In September 2017, a flash of blue light in the ice deep beneath the South Pole set researchers on a path to resolving this century-old riddle.
