Optical spectroscopy of type-2 LINERs
  Low-Ionisation Nuclear Emission-line Regions (LINERs) are the least luminous
and the most numerous among the local population of Active Galactic Nuclei
(AGN). They can be classified as type-1 or type-2 if their optical spectra show
or do not show, respectively, a broad component. It is associated with the
presence of a Broad Line Region (BLR) in these systems. However, recent studies
have proven that the classification of type-1 LINERs may be controversial,
since space- and ground-based spectroscopy provide contradicting results on the
presence of very broad components (Cazzoli et al. 2018). We have studied the
nuclear spectra of 9 type-2 LINERs with intermediate spectral resolution
HST/STIS data. We present the results on our analysis of the different spectral
components, and discuss the eventual presence of BLR components in type-2 LINER
galaxies, together with the possible presence of outflows, both in comparison
with type-1 LINERs. We have found a BLR component in 7 out of the 9 analysed
objects within the HST/STIS data.
