TL;DR: Radio spectral line radiation of water molecules at a wavelength of 1.35 centimeters has been measured from eight sources in the galaxy, which have extremely high brightness temperatures, and show many spectral features.
Abstract: Radio spectral line radiation of water molecules at a wavelength of 135 centimeters has been measured from eight sources in the galaxy The sources are less than I arc minute in diameter, have extremely high brightness temperatures, and show many spectral features Some spectral features are slightly polarized and some have changed greatly in intensity in a few weeks time

TL;DR: In this paper, a method and system of broadcast and distribution of OPTICAL FREQUENCY RADIATION is described, where the power level of the radio beam is maintained at a level which is a function of the pressure and dielectric constant of a gas.
Abstract: A METHOD AND SYSTEM OF TRANSMITTING AND DISTRIBUTING OPTICAL FREQUENCY RADIATION ARE DISCLOSED. THE POWER LEVEL OF THE RADIATION BEAM IS MAINTAINED AT A LEVEL WHICH IS A FUNCTION OF THE PRESSURE AND DIELECTRIC CONSTANT OF A GAS THROUGH WHICH THE BEAM IS TRANSMITTED. THE BEAM THROUGH THE GAS GENERATES ITS OWN WAVEGUIDE TO PREVENT BEAM DIVERGENCE THROUGH THE GAS.
