Researchers at the University of North Carolina at Chapel Hill have contributed to new insights into the most long-lived cosmic explosion ever recorded. The event was a gamma-ray burst that remained ...

The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope is located in the Canary Islands. Delayed gamma rays from deep space may provide the first evidence for physics beyond current ...

Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By ...

A new way of creating femtosecond, quasi-monoenergetic gamma-ray pulses has been proposed by Serge Kalmykov at the University of Nebraska-Lincoln and colleagues. Their scheme involves using a stack of ...

A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe work. Instead of behaving like a textbook blast, this eruption stayed ...

When the core of a massive star collapses, it can eject a jet of gas into space at nearly the speed of light. Collisions between the fast-moving gas and its surroundings, as well as within the jet ...

Gamma-ray bursts (GRBs) are among the most explosive and energetic celestial events that have been observed by astronomers. Since its first detection back in the 1960s, scientists have been observing ...

Teppei Katori and Pierre Lasorak at Queen Mary University of London have studied data from the the T2K neutrino experiment in Japan to search for signs of single gamma-ray emission from neutrino ...

According to the laws of physics, the speed of light is a fundamental barrier that cannot be broken - nothing is supposed to be able to travel faster than it. So astronomers were left baffled when ...

The European Space Agency's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum ...
