A near-infrared, optical and ultraviolet polarimetric and timing investigation of complex equatorial dusty structures
F. Marin, P. A. Rojas Lobos, J. M. Hameury +1
Context. From stars to active galactic nuclei, many astrophysical systems are surrounded by an equatorial distribution of dusty material that are, in a number of cases, spatially u…
Predicting the X-ray polarization of type-2 Seyfert galaxies
F. Marin, M. Dovciak, F. Muleri +2
Infrared, optical and ultraviolet spectropolarimetric observations have proven to be ideal tools for the study of the hidden nuclei of type-2 active galactic nuclei (AGN) and for c…
Unveiling the physics behind the spectral variations of "changing-look" quasars with optical polarimetry
F. Marin
A handful of active galactic nuclei (AGN) have shown strong spectral variations in the optical band between epochs that are years apart. The appearance or disappearance of broad em…
X-ray polarimetric signatures induced by spectral variability in the framework of the receding torus model
F. Marin, R. W. Goosmann, P. -O. Petrucci
Obscuring circumnuclear dust is a well-established constituent of active galactic nuclei (AGN). Traditionally referred to as the receding dusty torus, its inner radius and angular…
Modeling optical and UV polarization of AGNs III. From uniform-density to clumpy regions
F. Marin, R. W. Goosmann, C. M. Gaskell
A growing body of evidence suggests that part of, if not all, scattering regions of active galactic nuclei (AGNs) are clumpy. Hence. in this paper, we run radiative transfer models…
Dust in the wind I: spectropolarimetric signatures from disk-born outflows
F. Marin, R. W. Goosmann
In this first research note of a series of two, we conduct optical/UV investigations of the spectropolarimetric signatures emerging from the structure of quasars (Elvis 2000) appli…
UV and optical polarization modeling of thermal active galactic nuclei : impact of the narrow line region
F. Marin, R. W. Goosmann
In this research note, we start exploring the influence of the narrow line region (NLR) on the optical/UV continuum polarization of active galactic nuclei (AGN). We have upgraded o…
Modeling optical and UV polarization of AGNs II. Polarization imaging and complex reprocessing
F. Marin, R. W. Goosmann, C. M. Gaskell +2
We model the spectropolarimetric signature resulting from the radiative coupling between the innermost parts of active galactic nuclei (AGNs). We use a new public version of STOKES…
X-ray polarimetry as a new tool to discriminate reflection from absorption scenarios -- Predictions for MCG-6-30-15
F. Marin, R. W. Goosmann, M. Dovciak +5
We present modelling of X-ray polarisation spectra emerging from the two competing scenarios that are proposed to explain the broad Fe Kα line in the Seyfert 1 galaxy MCG-6-30-15.…
