"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 ...

During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will travel only the width of a proton, a tiny particle found within the nucleus of ...

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang ...

The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once ...

Normally when people think of gamma rays -- bursts of an incredibly high-energy form of light -- they are coming from out of this world, such as solar flares, exploding stars or black holes ...

"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." ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

But for a supernova to produce the strongest type of gamma-ray burst, the star must be some 30 to 40 times the size of the sun. This new powerful detection, so rare that we'll likely only observe ...

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

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 ...

The same result is obtained when studying the pulse-height from the gamma-rays emitted by different substances. There is, in this case, a continuous distribution of pulses from zero to a certain ...
