New experiments at CERN by an international team have ruled out a potential source of intergalactic magnetic fields. The existence of such fields is invoked to explain why we do not observe secondary ...
A new generation of gamma-ray detector known as AstroPix will fly aboard the agency’s Fly Foundational Robots mission, ...
These jets produce intense gamma-ray emission extending up to several teraelectronvolts, which are detected by ground-based telescopes. As these TeV gamma rays propagate across intergalactic space, ...
