The highest resolution images at ultra low radio frequencies are used to investigate the physical processes present in the radio emission from distant galaxies. Detections of spectral features from carbon atoms in a nearby galaxy are also presented and used to constrain the temperature and density of cold gas that is a key component of all galaxies. Show less
