Radio recombination lines are faint spectral features emitted when free electrons recombine with ions, cascading through high principal quantum levels and emitting photons at radio frequencies. Since ...
Active galactic nuclei (AGNs) are powered by accretion onto supermassive black holes and exhibit a rich diversity of temporal and spectral behaviour. Variability can occur on timescales from hours to ...
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 ...
