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 ...

which stirs and energize the wreckage around it to briefly emit a tremendous burst of gamma rays. According to the hypernova model, the explosion and the spinning black hole will continue to ...

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 ...

Gamma rays can be directed through the body to target tumours that cannot be treated with conventional surgery. The positioning and the intensity of the gamma ray sources are carefully calculated ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

In 2018, astronomers took the first-ever picture of a black hole, a fascinating and unprecedented glimpse of an event horizon. And as it turns out, the black hole — dubbed M87* and located some ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

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 authors report the first observation of a high-energy gamma-ray flare in over a decade from the supermassive black hole M87, based on nearly simultaneous spectra of the galaxy spanning the ...
