Fast radiative shocks in dense media - III. Properties of the emission
Abstract
The evolution of fast, radiative shocks in a high-density medium is presented. Ionizing spectra and approximate broad-band light curves of the shocked gas are calculated. Emergent shock spectra, as seen by a distant observer, are obtained from photoionization models. The emergent spectra have a power-law shape F_nu~nu^-alpha with mean spectral index alpha~0.6-1.0 in the energy range 0.01-10 keV, and have a high-energy cut-off corresponding to the original shock velocity. It is shown that the models exhibit promising features that may account for some photometric and spectral properties of active galactic nuclei.
