The blast lasted for roughly three Earth days ... we can combine direct imaging of the near event horizon regions during gamma-ray flares from particle acceleration events and test theories ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

Another member of the team, John Finley, assistant professor of physics at Purdue, says the current models describing such gamma-ray flares predict that variations should occur, but on the scale of ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete ...

The European Commission recently established a planned gamma-ray observatory as a European Research Infrastructure Consortium, or ERIC, which will expedite the construction of the telescope and ...

is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma ray emissions. Inaccurate and incomplete data ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
