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 ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...
