This paper discusses the scattering in the solar corona of the radiation emitted by the solar disk. We obtain expressions for the emissivity which permit to deduce the spectral characteristics of the scattered radiation. With these expressions, assuming a Maxwellian distribution for the velocities of the scattering ions and a simple spectral shape of the exciting radiation, we produce approxima...

Abstract A theoretical prediction method of the scattering fan tone radiation from a turbofan inlet duct by airframe fuselage is presented. The noise modelled an acoustic disc source that represents sound field at termination. Adjacent to cylindrical scatters radiation. valid for upstream pressure on affected refraction as it propagates through boundary layer. This effect known layer shielding ...

Semi-analytic models of galaxy formation postulate the existence of virialized gaseous halos around galaxies at high redshifts. A small fraction of the light emitted by any high-redshift quasar is therefore expected to scatter off the free electrons in the halo of its host galaxy. The broadening of the scattered emission lines of the quasar can be used to measure the temperature of these electr...
