These galaxies – some hundreds of them and called the Little Red Dots – are very red and compact, and visible only during ...

Moreover, discrepant degradation rates of the emitters lead to instability of the emission spectra, and rare-earth metals (e.g., Y, Ce) or toxic metals (e.g., Cd, Pb) are always used in the phosphors.

A never-before-seen group of galaxies, known as the Little Red Dots, were first spotted by the new Webb Telescope.

Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a ...

By using the light that’s emitted from stars, Ada explains how this light has been a revealing insight to the composition of the star. Use the animation and laboratory emission spectra of different ...

Thermal emission is one of the phenomena in which the density of states of the radiation field plays an important role. The thermal emission spectrum of a perfect blackbody is determined by the ...

XS operates through the interaction of X-rays with matter, introducing dependencies on polarization, energy, and momentum. The RIXS spectra are typically represented as a combination of X-ray emission ...

Astronomers break the light down into the different frequencies and visualize them with a chart, called a spectrum. Sometimes, the spectrum contains emission lines, which are ranges of frequencies ...

Recently, researchers at the High-Altitude Water Cherenkov observatory in Mexico reported the observation of ultra-high ...
