Scattered synchrotron emission and a giant torus revealed in polarized light in the nearest radio galaxy Centaurus A

F. Marin, D. Hutsemékers, C. -Z. Jiang +5

Centaurus A (Cen A) is the closest radio galaxy and a prime example of a low-luminosity active galactic nucleus (AGN), exhibiting complex emissions across the electromagnetic spect…

X-ray properties of coronal emission in radio quiet Active Galactic Nuclei

Sibasish Laha, Claudio Ricci, John C. Mather +5

Active galactic nuclei (AGN) are powerful sources of panchromatic radiation. All AGN emit in X-rays, contributing around of the AGN bolometric luminosity. The X-ray e…

Revealing the burning and soft heart of the bright bare AGN ESO 141-G55: X-ray broadband and SED analysis

Delphine Porquet, James N. Reeves, Scott Hagen +4

[Abridged] ESO 141-G55 is a nearby X-ray bright BLS1, which has been classified as a bare AGN due to the lack of warm absorption along its line-of-sight, providing an unhampered vi…

X-ray polarization from parsec-scale components of active galactic nuclei: observational prospects

J. Podgorný, F. Marin, M. Dovčiak

We present a broad analysis of X-ray polarimetric observational prospects for radio-quiet active galactic nuclei (AGN), focusing on the role of parsec-scale components. We provide…

Simple numerical X-ray polarization models of reflecting axially symmetric structures around accreting compact objects

J. Podgorný, M. Dovčiak, F. Marin

We present a series of numerical models suitable for X-ray polarimetry of accreting systems. Firstly, we provide a spectropolarimetric routine that integrates reflection from inner…
