To get insight in the nature of the ionized gas in the nuclear region of LINERs we have performed a study of HST Halpha imaging of 32 LINERs. The main conclusion from this analysis is that for the large majority of LINERs (84%) an unresolved nuclear source has been identified as well as extended emission with equivalent sizes ranging from few tens till about hundredths of parsecs. Their morphologies appear not to be homogeneous being basically grouped into three classes:nuclear outflow…

The Shocking Power Sources of LINERs
The majority of low-ionization nuclear emission-line regions (LINERs) harbor supermassive black holes with very low accretion rates. However, the accretion flows do not produce enough ionizing
Suzaku observation of the LINER NGC 4102
TLDR
There is strong evidence that NGC 4102 is a Compton-thick AGN, as suggested by the Swift/BAT detected intrinsic continuum and the presence of a strong narrow, neutral FeKα emission line in the Suzaku spectrum of the source.
Optical spectroscopy of type 2 LINERs
Abstract 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
The subarcsecond mid-infrared view of local active galactic nuclei – I. The N- and Q-band imaging atlas
We present the first subarcsecond-resolution mid-infrared (MIR) atlas of local active galactic nuclei (AGN). Our atlas contains 253 AGN with a median redshift of z = 0.016, and includes all publicly
Dependence of Optical Active Galactic Nuclei Identification on Stellar Population Models
We have conducted a study to quantify the systematic differences resulting from using different stellar population models (SPM) in optical spectroscopic identification of type II active galactic
Quasars Classes and Their Relationships
Most of the questions in this chapter deal with sources that do not show the “classical” broad emission-line spectrum that characterizes the majority of known AGNs at high and low redshift. If that
Quasars in the Cosmic Environment
We now consider the environment of quasars in the widest possible sense, from the circumnuclear regions to very large scales of hundreds of kiloparsecs. The circumgalactic environment of nearby

Synapses of active galactic nuclei: - Comparing X-ray and optical classifications using artificial neural networks
(Abridged) Many classes of active galactic nuclei (AGN) have been defined entirely throughout optical wavelengths while the X-ray spectra have been very useful to investigate their inner regions.
