The Doppler effect refers to a noticeable change in frequency of light or sound waves as the distance between the source and the observer changes. It is either the source or the observer of a wave is ...

A light beam with orbital angular momentum can produce the rotational analog of the Doppler effect on an ion. A vortex light beam is one whose wave fronts rotate like a corkscrew, endowing the beam ...

We can't witness the birth of our own Solar System, but the Atacama Large Millimeter/submillimeter Array (ALMA) is providing a picture of how it may have happened. ALMA spotted signs of three giant ...
