Extract

Free-free absorption by thermal electrons attenuates low frequency radio waves and such absorption will indicate the presence of ionized hydrogen. The Gum Nebula contains bright H-alpha emission regions and therefore it is not surprising that the region appears as an area of low brightness on low frequency continuum maps.
