PORTILLA, José Gregorio; RODRIGUEZ-ARDILA, Alberto  e  TEJEIRO, Juan Manuel. CINEMÁTICA DE LA REGIÓN EMISORA DE LÍNEAS CORONALES OBSERVADAS EN GALAXIAS SEYFERT. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2012, vol.36, n.141, pp.473-490. ISSN 0370-3908.

Two sets of spectra selected by their prominent coronal line emission were analyzed with the purpose of characterizing the kinematics of clouds emitting coronal lines. Values of full width at the half the maximum (FWHM), shift of the peak emission (Δv), kurtosis and asymmetry both of coronal lines and some low ionization lines (these latter for comparison) are presented. For the majority of the objects, no correlation between ionization potential and FWHM it is observed, particularly if [Fe _X] λ6374 and [Fe _XI] λ7892 lines are included. Regarding the shifting of the peak emission most of the objects show blueshift whereas just 15 % showed a slight redshift. There are weak correlations between FWHM and Δv for coronal lines. Finally, there is some indication that the radio luminosity has influence in the shift of the peak emission of coronal lines suggesting that the jet radio is intervening in the outflows of these lines.
