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 ...

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 ...

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 ...

Supernovae are classified primarily based on their spectral characteristics, notably the presence or absence of hydrogen lines, leading to type I (no hydrogen) and type II (hydrogen present) ...

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 ...

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 ...
