Origin of the Continuum in High Redshift Radio Galaxies

1999
Deep Keck spectropolarimetry has been obtained of 9 high redshift radio galaxies (HzRGs) with z~2.5. All objects exhibit a remarkably similar continuum shape with a flattening around 1400A and a dip around 2200A (other results are in Fosbury et al. 1999). This can be explained by a simple ’scattering sphere’ model in which standard Galactic dust grains

Radio Continuum Emission from Galaxies

1975
The continuum radio emission detected from external galaxies is produced either by thermal process or by the synchrotron process with the latter dominating in most cases. For the synchrotron process the volume emissivity is given by $$ \varepsilon \left( \upsilon \right) = {\rm{n}}{\mkern 1mu} {{\rm{B}}^{\frac{{{\rm{1 + }}\gamma }}{2}}} {\upsilon ^{

Radio Continuum Emission from Sculptor Galaxies

Publications of the Astronomical Society of Australia, 1986
AbstractThe five major members of the Sculptor Group of galaxies and NGC 45 have been observed with the Molonglo observatory synthesis telescope. NGC 247 and NGC 300 were not detected and upper limits to their 843 MHz flux densities are given. Radio emission from NGC 7793 is discussed with particular attention to its morphology, radial dependence ...
