and they activate interstellar matter to emit spectral emission lines of X-rays and gamma rays specific to the elements. In this research, we will establish an imaging method to visualize line X-ray ...

Caption The top panel shows the power-law evolution of the energy of gamma-ray line (blue) detected in GRB 221009A, while the prompt emission (black) and afterglow (gray) of this burst are plotted ...

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 ...

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 ...

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 ...

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 ...

These observations "blur the line between these two types of emission, suggesting that gamma-ray glows often morph into intense pulses", Dwyer explained. Lightning often follows these intense ...

Gamma-ray bursts (GRBs) are intense bursts of gamma ... "As the jet crosses the line-of-sight, an observer will see light produced first by one side of the jet, then the jet center, and finally ...

"StarBurst represents a significant leap forward in gamma-ray astronomy," said Richard S. Woolf, Ph.D., research physicist with NRL's Space Science Division. "Our team at NRL has drawn upon years ...

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 ...
