An active galactic nucleus is the brightest source of electromagnetic radiation in the Universe, believed to be powered by a supermassive black hole at its core. There are two main types of active galactic nuclei, though the differences may be down to varying viewing angles. Or are they? 
Astronomy: Unifying active galactic nuclei
Properties of companion galaxies strengthen the idea that the probability of the inner regions of an active galaxy being hidden from our view by dust depends on environmental and evolutionary factors.
AGN Luminosity and Stellar Age: Two Missing Ingredients for AGN Unification as Seen with iPTF Supernovae
Active galactic nuclei (AGNs) are extremely powerful cosmic objects, driven by accretion of hot gas upon super-massive black holes. The zoo of AGN classes is divided into two major groups, with Typ
The Host-galaxy Properties of Type 1 versus Type 2 Active Galactic Nuclei
The unified model of active galactic nuclei (AGNs) proposes that different AGN optical spectral types are caused by different viewing angles with respect to an obscuring 'torus'. Therefore, this
Testing the Evolutionary Link between Type 1 and Type 2 Quasars with Measurements of the Interstellar Medium
In a popular scenario for the coevolution of massive black holes and galaxies, major mergers of gas-rich galaxies fuel vigorous star formation and obscured (type 2) quasar activity until energy
The [OIII] profiles of infrared-selected active galactic nuclei: More powerful outflows in the obscured population
We explore the kinematics of ionized gas via the [O III] $\lambda$5007 emission lines in active galactic nuclei (AGN) selected on the basis of their mid-infrared (IR) emission, and split into
The Relation between Luminous AGNs and Star Formation in Their Host Galaxies
We study the relation of active galactic nuclei (AGNs) to star formation in their host galaxies. Our sample includes 205 Type-1 and 85 Type-2 AGNs, 162 detected with Herschel, from fields surrounding
A Main Sequence for Quasars
The last 25 years saw a major step forward in the analysis of optical and UV spectroscopic data of large quasar samples. Multivariate statistical approaches have led to the definition of systematic
Galaxy and Mass Assembly (GAMA): active galactic nuclei in pairs of galaxies
There exist conflicting observations on whether or not the environment of broad and narrow line AGN differ and this consequently questions the validity of the AGN unification model. The high
The incidence of nuclear activity in galaxy pairs with different morphologies (E+E), (E+S) and (S+S)
We analysed 385 galactic spectra from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) that belong to the catalog of isolated pairs of galaxies by Karachentsev. The spectra corresponds to
Emission Line Galaxies and Active Galactic Nuclei in WINGS clusters
We present the analysis of the emission line galaxies members of 46 low redshift (0.04 < z < 0.07) clusters observed by WINGS (WIde-field Nearby Galaxy cluster Survey, Fasano et al. 2006). Emission


On the Unification of Active Galactic Nuclei
The inevitable spread in properties of the toroidal obscuration of active galactic nuclei (AGNs) invalidates the widespread notion that type 1 and 2 AGNs are intrinsically the same objects, drawn
Blue Low Surface-Brightness Galaxies
The first results from an analysis of CCD photometry of blue low surface-brightness galaxies are presented. The galaxies have a wide range of morphologies, luminosities and ages — all appear to be
Unified models for active galactic nuclei and quasars
Because the critical central regions of Active Galactic Nuclei (AGN) and quasars are strongly nonspherical but spatially unresolved, orientation effects have been the source of much confusion. In
Active Galactic Nucleus Pairs from the Sloan Digital Sky Survey. I. The Frequency on ~5-100 kpc Scales
Galaxy-galaxy mergers and close interactions have long been regarded as a viable mechanism for channeling gas toward the central supermassive black holes (SMBHs) of galaxies which are triggered as
Disk-outflow Connection and the Molecular Dusty Torus
Toroidal obscuration is a keystone of AGN unification. There is now direct evidence for the torus emission in infrared, and possibly water masers. Here I summarize the torus properties, its possible

The model relates the width of the broad emission lines of active galactic nuclei (AGNs) to the Keplerian velocity of an accretion disk at a critical distance from the central black hole and shows that the observed range of Hbeta FWHMs from broad-line to narrow-line type 1 AGNs is well reproduced as a function of the accretion rate.
AGN Population in Compact Groups Galaxies
The aim of this study is to establish the frequency of nuclear activity (AGN and star formation) in galaxies belonging to Compact Groups (CGs) and to charac...
LINER nuclei, which are present in many nearby galactic bulges, may be the manifestation of low-rate or low-radiative-efficiency accretion onto supermassive central black holes. However, it has been
On the Nature of Low-Luminosity Narrow-Line Active Galactic Nuclei
There is clear observational evidence that some narrow-line (type 2) active galactic nuclei (AGNs) have a hidden broad-line region (BLR) and are thus intrinsically broad-line (type 1) AGNs. Does this
The host galaxies of active galactic nuclei
We examine the properties of the host galaxies of 22 623 narrow-line active galactic nuclei (AGN) with 0.02 < z < 0.3 selected from a complete sample of 122 808 galaxies from the Sloan Digital Sky
