For that, you need something like this gamma-ray spectroscope ... showing different spectra for each. [mihai.cuciuc] took inspiration for the Pomelo from this DIY spectrometer as well as the ...

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 ...

The tour ends with gamma rays, the potentially deadly radiation ... To find out more about the spectrum, see the links in Resources. To convert metric measurements discussed in this feature ...

Another unusual feature of Markarian 421 is that it is bright at both the low and high ends of the energy spectrum, but emits only a weak signal in certain regions of gamma rays. "This particular ...

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against ...

Where are the particles responsible for the emission of gamma rays accelerated ... complete across the entire electromagnetic spectrum." Thanks to the collaboration between these and other ...

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The ...

The wave-length and quantum energy of many of the stronger lines in the complicated gamma ray spectrum have been determined by different methods, with concordant results. It has been difficult to ...

Mysterious gamma rays; snake-eating snake ...

These two factors limit the number of isotopes that can be used successfully for Mössbauer spectroscopy. The most used is 57 Fe, which has both a very low energy gamma-ray and long-lived excited state ...

Before this research, scientists didn't recognize that some nearby gamma-ray bursts are also part of this massive structure. The finding is extraordinary because the Hercules-Corona Borealis Great ...
