One new theory could put some long-standing physics mysteries to rest. A recent astrophysical model suggests that three different types of high-energy “cosmic messenger particles” could all originate ...

New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their environments. One of the biggest mysteries ...

One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals ...
