Optical spectroscopy of local type-1 AGN LINERs

Abstract

In this talk, I will present the highlights from our recent study of  22
local (z < 0.025) type-1 LINERs from the Palomar Survey, on the basis of
optical long-slit spectroscopic observations taken with TWIN/CAHA,
ALFOSC/NOT and HST/STIS (Cazzoli et al. 2018, MNRAS 480, 1106–1162).
In this study, we explored the AGN-nature of these type-1 LINERs by
studying the broad (BLR-originated) Hα component. Then, we derived
reliable interpretation for the different component of emission lines by
studying their kinematics and ionization mechanism. Finally, we studied
the neutral gas in the nuclei of these LINERs by modeling of the NaD
absorption.
