| Abstract: |
SOAR/Goodman spectroscopy is employed to detect
the coronal lines [Fe VII] 3759, 5159, and 6087 Å, [Ne V] 3423 Å
and [Fe X] 6083 Å, the former three suitable to determine the temperature
and density of the high-ionization gas. The spectra allow us to fully
characterize the profiles of the most conspicuous lines (asymmetries, shifts from
the centroid position and line
width). The combined results allow us to detect signatures of outflows in the coronal gas and
thus set up constrains on the origin of the CLs in AGNs. In addition, AO GEMINI/NIFS
IFU spectroscopy is used to study the coronal gas morphology at spatial scales
of a few parsecs in the Seyfert 2 galaxy NGC 1068. We found that the gas distribution is
rather inhomogeneous and asymmetric. From the comparison of the CL [Mg VIII]
with the VLA 6 cm radio emission we found evidence that the CL gas kinematics and
morphology is strongly related to the radio jet morphology. All above results allow
us to confirm the role that coronal lines have to trace outflows at the inner tens of
parsecs of AGNs. |
