... of the biggest mysteries in astroparticle physics - where do very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays all come from, now think that all three high-energy phenomena could have a common origin; powerful jets...
... an atomic nucleus in the Antarctic ice. After adjusting their sights, the two observatories also picked up a flare of high-energy gamma rays at the same location, indicating very convincingly that TXS 0506+056 was the most likely source...
... some of these objects are only seen to emit pulses of radio waves, while others only emit pulses of high energy gamma rays and it may simply be down to looking at them from a different perspective. Pulsars are...
