London, Oct 12 (ANI): The Antarctic Impulsive Transient Antenna (ANITA) that makes use of thick Antarctic ice and a giant balloon has unexpectedly detected mysterious, ultra-high-energy cosmic rays.
Had Fermi and VERITAS not found gammaray emissions from starburst galaxies, he notes, "it would have been back to the drawing board" for understanding the origin of cosmic rays.
If this is so, then the physical processes of producing cosmic rays must be as common as those which produce star light.

More problematic, these simulations neglected cosmic rays and magnetic fields, which provide a comparable pressure support in comparison to turbulence in our Galaxy, and are known to couple dynamically and thermally to the gas.
In addition to shedding light on our cosmic neighborhood, the results offer an explanation for a decades-old mystery on why we measure more incoming high-energy cosmic rays on one side of the sun than on the other.
Using measurements of ultra-high energy cosmic rays on a global scale, we now have a completely different means of verifying that the field directions we derived from IBEX are consistent," said Nathan Schwadron, lead scientist for the IBEX Science Operations Center at the UNH Institute for the Study of Earth, Oceans, and Space.
The new system will store and analyze observational data on cosmic rays, which include protons, gamma rays, and neutrinos, and will be used for ICRR's various domestic and international joint research projects in astrophysics and particle physics.
