Radio Seyferts and the forbidden-line region

We describe a model in which the expansion of the radio-emitting components in Seyfert 2 nuclei compresses and accelerates the ambient medium by means of Shockwaves. When the expansion velocity of the component has decreased to ∼400 km s−1, the compressed gas cools and has the properties attributed...

Description
Summary:We describe a model in which the expansion of the radio-emitting components in Seyfert 2 nuclei compresses and accelerates the ambient medium by means of Shockwaves. When the expansion velocity of the component has decreased to ∼400 km s−1, the compressed gas cools and has the properties attributed to the forbidden-line region. This readily accounts for the intimate relationship between the radio continuum emission and the forbidden-line region.
