XRISM measurements map gas velocities in the Perseus and Virgo clusters, separating black hole-driven turbulence from merger-driven motion using high-resolution X-ray spectroscopy.

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

(Nanowerk News) Optical frequency comb (OFC) provides equidistant comb lines in broad bandwidth, and each comb line corresponds to an absolute optical frequency, which is similar as a comb (or rule) ...
