Bringing the concepts of pulse shaping and frequency combs together allows the generation of waveforms with both controllable ultrafast time structure and long-term coherence. Two-photon absorption ...

Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.
