Astrocombs: Recent Advances
Precision calibration of astronomical spectrographs is essential to the hunt for exoplanets, the study of cosmology and determining variation of the fundamental constants. Frequency combs (‘astrocombs’) can serve as real-time references, providing unprecedented accuracy and precision. Here we provide a brief overview over demonstrated astrocombs and recent advances.
