How Advances in Radio Interferometry are Providing New Windows on the Submillimeter U

The Atacama Large Millimeter/submillimeter Array (ALMA) is the culmination of over 50 years of development of radio synthesis interferometers and more recent major advances in mm and sub-mm instrumentation. ALMA’s angular resolution will be as small as 5 milliarcseconds providing the capability to, for example, image the gas kinematics in protostars and disks around young stars and to image the redshifted dust continuum emission from galaxies at epochs of formation as early as z=10.
