Stellar spectroscopy is the principal method by which astronomers decode the physical properties of stars from their emitted light. By dispersing a star’s radiation into its constituent wavelengths, ...
Far-infrared spectroscopy probes the cold and dust-enshrouded regions of the Universe by measuring electromagnetic radiation in the 30–300 μm band. This regime encompasses the principal cooling lines ...
Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
