Abstract

We present high-resolution observations of six Seyfert 1 galaxies in the 2 μm region. We detected the [Si vi] 1.96 μm coronal line in all the galaxies and analyzed its profile, finding it to be variable in width from object to object, from very narrow profiles (FWHM ∼ 300 km s^-1) to profiles approaching the width of the broad lines. The coronal region seems to be placed differently in different galaxies, and in some cases the infrared coronal lines are useful as a probe of the structure of the broad-line region.
