Radio Astronomy, ALMA & Interferometric Arrays: Observation, Measurement & Evidence

Radio astronomy measures wavelengths from millimeters to meters that reveal cold molecular gas, synchrotron radiation, pulsars, jets, the CMB, and many sources hidden from optical view. Radio arrays study cold matter, astrochemistry, star formation, black-hole jets, planet-forming disks, and high-redshift galaxies.
