The sun's inner corona, the hottest part of our star's atmosphere, appears faint yellow in a time-lapse made from images taken by the ASPIICS coronagraph aboard Proba-3. An international team of ...

At each triennial meeting of the General Assembly, the International Astronomical Union (IAU) carefully reviews the list of astrophysically most important spectral lines that it maintains. The IAU ...

Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...

Stimulated Raman Scattering (SRS) has been developed as an essential quantitative contrast for chemical imaging in recent years. However, the spectral resolution of the mainstream SRS modalities is ...

High resolution and sensitivity are critical in nuclear magnetic resonance (NMR) spectroscopy. Both can be overdoubled when using heteronuclear decoupling. This enables the severance of overlapping ...

1. If Notes 2 or 4 are not listed, then the band limits are the Doppler-shifted frequencies corresponding to radial velocities of ± 300 km/s (consistent with line radiation occurring in our Milky Way ...
