Nuclear obscuration in active galactic nuclei

  title={Nuclear obscuration in active galactic nuclei},
  author={Cristina Ramos Almeida and Claudio Ricci},
  journal={Nature Astronomy},
The material surrounding accreting supermassive black holes connects the active galactic nucleus with its host galaxy and, besides being responsible for feeding the black hole, provides important information on the feedback that nuclear activity produces on the galaxy. In this Review, we summarize our current understanding of the close environment of accreting supermassive black holes obtained from studies of local active galactic nuclei carried out in the infrared and X-ray regimes. The… Expand

Nature of quasar disk-wind
The brightest persistent astrophysical sources in the universe are quasars, a group of active galactic nuclei (AGN) that appear star-like and radiate across all wavelengths. The emitted radiation isExpand
X-Ray Constraint on the Location of the AGN Torus in the Circinus Galaxy
The location of the obscuring “torus” in an active galactic nucleus (AGN) is still an unresolved issue. The line widths of X-ray fluorescence lines originating from the torus, particularly Fe Kα,Expand
Properties of the Obscuring Torus in NGC 1052 from Multiepoch Broadband X-Ray Spectroscopy
Obscuration of the innermost parts of active galactic nuclei (AGN) is observed in the majority of the population both in the nearby universe and at high redshift. However, the nature of theExpand
The interstellar and circumnuclear medium of active nuclei traced by H i 21 cm absorption
This review summarises what we have learnt in the last two decades based on H i 21 cm absorption observations about the cold interstellar medium (ISM) in the central regions of active galaxies andExpand
Dissecting the active galactic nucleus in Circinus – II. A thin dusty disc and a polar outflow on parsec scales
Recent observations which resolved the mid-infrared (MIR) emission of nearby active galactic nuclei (AGNs), surprisingly revealed that their dust emission appears prominently extended in the polarExpand
Imaging the Active Galactic Nucleus Torus in Cygnus A
We present the first direct imaging of what may be the thick torus in the active galactic nucleus (AGN) of the archetype powerful radio galaxy Cygnus A, using the Jansky Very Large Array at 18-48Expand
Dust Formation in AGN Winds
Infrared observations of active galactic nucleus (AGN) reveal emission from the putative dusty circumnuclear 'torus' invoked by AGN unification, that is heated up by radiation from the centralExpand

Nuclear molecular outflow in the Seyfert galaxy NGC 3227
ALMA observations have revealed nuclear dusty molecular disks or tori with characteristic sizes 15−40 pc in the few Seyferts and low -luminosity AGN that have been studied so far. These structuresExpand

Context. In recent decades, several multiwavelength studies have been dedicated to exploring the properties of the obscuring material in active galactic nuclei (AGN). Various models have beenExpand


A direct image of the obscuring disk surrounding an active galactic nucleus
Active galactic nuclei (AGN) are generally accepted to be powered by the release of gravitational energy in a compact accretion disk surrounding a massive black hole,; such disks are also thoughtExpand
Obscuring Material around Seyfert Nuclei with Starbursts
The structure of obscuring matter in the environment of active galactic nuclei with associated nuclear starbursts is investigated using three-dimensional hydrodynamical simulations. Simple analyticalExpand

We simulate the growth of galaxies and their central supermassive black holes by implementing a suite of semi-analytic models on the output of the Millennium Run, a very large simulation of theExpand
Radiation-driven Fountain and Origin of Torus around Active Galactic Nuclei
We propose a plausible mechanism to explain the formation of the so-called obscuring tori around active galactic nuclei (AGNs) based on three-dimensional hydrodynamic simulations including radiativeExpand

Dusty winds in active galactic nuclei: reconciling observations with models
This letter presents a revised radiative transfer model for the infrared (IR) emission of active galactic nuclei (AGN). While current models assume that the IR is emitted from a dusty torus in theExpand
