We report the results of a spectropolarimetric survey of the CfA and 12 μm samples of Seyfert 2 (S2) galaxies. Polarized (hidden) broad-line regions (HBLRs) are confirmed in a number of galaxies, and several new cases (F02581-1136, MCG -3-58-7, NGC 5995, NGC 6552, NGC 7682) are reported. The 12 μm S2 galaxy sample shows a significantly higher incidence of HBLRs (50%) than its CfA counterpart (30%), suggesting that the latter may be incomplete in hidden active galactic nuclei. Compared to the… 

Seyfert 2 Galaxies with Spectropolarimetric Observations

We present a compilation of radio, infrared, optical, and hard X-ray (2-10 keV) data for a sample of 90 Seyfert 2 galaxies (Sy2s) with spectropolarimetric observations (41 Sy2s with detection of

The dichotomy of Seyfert 2 galaxies: intrinsic differences and evolution

We present a study of the local environment (≤200 h −1 kpc) of 31 hidden broad line region (HBLR) and 43 non-HBLR Seyfert 2 (Sy2) galaxies in the nearby universe (z ≤ 0.04). To compare our findings,

Are Seyfert 2 Galaxies without Polarized Broad Emission Lines More Obscured

New XMM-Newton data of seven Seyfert 2 galaxies with optical spectropolarimetric observations are presented. An analysis of the 0.5–10 keV spectra shows that four Seyfert 2 galaxies with polarized

Dust Morphology of Hidden Broad-Line Region and Non-Hidden Broad-Line Region Seyfert 2 Galaxies

We investigate the nuclear dust properties of hidden broad-line region (HBLR) and non-HBLR Seyfert 2 galaxies. Optical images obtained from the Hubble Space Telescope for a selected sample of HBLR

The dust geometric distribution in Seyfert 1 and Seyfert 2 galaxies, isolated and in interaction

We analyse the mid-infrared (MIR) spectra of 39 Seyfert galaxies observed with the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope. Our sample consists of 19 Seyfert type 1 (Sy1)

An XMM–Newton spectral survey of 12 μm selected galaxies – II. Implications for AGN selection and unification

We present a multi-waveband analysis of a 126-galaxy sub-sample of the 12 μm galaxy sample ( 12MGS), for which we have carried out a detailed X-ray spectral analysis in a previous paper. We determine

Near-infrared spectroscopy of nearby Seyfert galaxies. II. Molecular content and coronal emission

We present sub-arcsec near-infrared 1.5 – 2.5 µm moderate resolution long-slit spectra of eight nearby Seyfert galaxies (z <0.01), both parallel to the ionization cone and perpendicular to it. These

On the nature of the near-UV extended light in Seyfert galaxies

We study the nature of the extended near-UV emission in the inner kiloparsec of a sample of 15 Seyfert (Sy) galaxies which have both near-UV (F330W) and narrow-band [O iii] high-resolution Hubble

The K-band properties of seyfert 2 galaxies (Research Note)

Aims. It is well known that the [O iii]λ5007 emission line and hard X-ray (2−10 keV) luminosities are good indicators of AGN activities and that the near and mid-infrared emission of AGN originates


We have examined the physical conditions within a bright emission-line knot in the inner narrow-line region (NLR) of the Seyfert 2 galaxy Mrk 573 using optical spectra and photoionization models. The

We report the results of 20, 6, and 2 cm VLA and 1.5 cm OVRO observations of two similar radio-quiet active galaxy and quasar (AGN) samples: the optically selected CfA Seyfert galaxies and the

Spectropolarimetry of high-polarization Seyfert 2 galaxies and unified Seyfert theories

Spectropolarimetry was used to study eight high-polarization Seyfert 2 galaxies. In four of them (Mrk 3, Mrk 348, Mrk 463E, and NGC 7674), evidence was found for a hidden broad-line region (BLR),

Infrared Spectroscopy of Seyfert 2 Galaxies: A Look through the Obscuring Torus? II.
