Cosmic-ray geology
What can rocks tell us about the history of cosmic rays? More than you might think.
Starburst Galaxies: Explainably Juicy
Could star-forming galaxies answer some of the mysteries of high-energy astrophysics? Signs point to yes.
Studying the Earth’s Interior with (atmospheric) Neutrinos
Astrophysicists and their experiments normally look up, not down. IceCube is an exception. Here the density profile of the Earth is measured using neutrinos.
Antineutrinos, Left-Handed Molecules, and You
Earth life has a definite preference for particular kinds of molecules. Where did life get its taste for left-handed amino acids?
Where are the IceCube neutrinos coming from? (part 2)
We still don’t know where the IceCube astrophysical neutrinos are coming from. Today’s paper places constraints on what percentage are coming from the Galactic plane.
The Origin of the IceCube Neutrinos: An Ongoing Mystery
Star-forming galaxies have been eliminated as the top suspects for the origin of the IceCube neutrinos, leaving behind a dwindling list of unexpected possibilities.
