Galaxies such as NGC253 and M82 which radiate strongly in the far infrared are studied. They produce a typical thermal emission also seen in a wide range of galaxies which is considered to be a sign of extensive star formation. The use of submillimeter observations to differentiate between thermal or nonthermal synchrotron emission in radio quiet quasars and Seyfert 1 galaxies is discussed. Radio loud active galaxies such as blazars, have non-thermal spectra which become optically thin at about 1 mm. Monitoring this emission is shown to be a crucial test of the emission mechanisms of the relativistic jets believed to power blazars.
