Yes. Each spectral line corresponds to a specific energy transition related to a particular atom — and thus, element. Astronomers analyze such lines to tell us what celestial objects are made of. In ...

Astronomers from the University of California (UC), Berkeley and elsewhere have performed spectroscopic and photometric study of a peculiar supernova designated SN 2021ukt, which underwent a ...

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using ...

Reddened starlight originates from three distinct mechanisms, each discernible through specific spectral analysis. The Doppler effect causes spectral lines to shift towards longer wavelengths ...

One of the most detailed spectrographs ever recorded of the Sun has revealed hundreds of missing wavelengths—gaps in the solar spectrum that scientists have yet to identify. Despite over 200 years of ...

When designing with interconnects, we're often concerned about issues such as crosstalk and reflections. We frequently ask for models from the manufacturers so we can run simulations to determine the ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark ...

Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...
