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 ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

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 ...

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

Taking a look back over the last twelve months, here are several of the biggest science stories in physics this year, as well ...

The Gamma-Ray Astrophysics Research group at Michigan Tech, led by founder Dr. Petra Huentemeyer, is designed to observe gamma rays and cosmic rays between about 100 GeV up to about 100 TeV. TeV gamma ...

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 ...
