X-ray polarization of the Compton-thin Seyfert galaxy NGC 5506 with IXPE
Daniele Tagliacozzo, Alessandro Leonardo Lai, Andrea Gnarini +14
We report on the observation of the Compton-thin Seyfert galaxy NGC~5506 performed with the Imaging X-ray Polarimetry Explorer (IXPE). The observation, with a net observing time of…
EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics
Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137
The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…
A XRISM view of the iron line complex in NGC 1068: Rethinking the prototypical Compton-thick AGN
S. Bianchi, B. Vander Meulen, E. Bertola +32
We analyze a XRISM/Resolve observation of NGC1068, focusing on the Fe K and Fe K fluorescent lines and on the Fe XXV and Fe XXVI emission complexes. Line centroid energies, i…
XPE and VLT /FORS2 polarimetry challenge the Seyfert-1.9 classification of MCG-05-23-16
Frédéric Marin, Daniele Tagliacozzo, Francesco Ursini +21
We report the third observation of the Seyfert-1.9 active galactic nucleus (AGN) MCG-05-23-16 with the Imaging X-ray Polarimetry Explorer (\textit{IXPE}), together with optical spe…
X-ray polarization in radio-quiet AGN: Insights from the wedge corona model using Monte Carlo simulations
D. Tagliacozzo, S. Bianchi. V. Gianolli, A. Gnarini +4
In this study, we present novel calculations of X-ray polarization from radio-quiet and unobscured active galactic nuclei (AGNs) using the Monte Carlo code MONK, which includes all…
First X-ray polarimetric view of a Low-Luminosity Active Galactic Nucleus: the case of NGC 2110
Sudip Chakraborty, Ajay Ratheesh, Daniele Tagliacozzo +20
Low-Luminosity Active Galactic Nuclei (LLAGN) provides a unique view of Comptonization and non-thermal emission from accreting black holes in the low-accretion rate regime. However…
A second view on the X-ray polarization of NGC 4151 with IXPE
V. E. Gianolli, S. Bianchi, E. Kammoun +21
We report on the second observing program of the active galactic nucleus NGC 4151 with simultaneous Imaging X-ray Polarimetry Explorer (IXPE; {\sim}750 ks), NuSTAR ({\sim}60 ks), X…
Unobscured radio-quiet Active Galactic Nuclei under the eyes of IXPE
V. E. Gianolli, S. Bianchi, P-O. Petrucci +8
We present the results of the X-ray polarimetric analyses performed on unobscured radio-quiet Active Galactic Nuclei (AGN) with the Imaging X-ray Polarimetry Explorer (IXPE), with…
A remarkably stable accretion disc in the Seyfert galaxy MCG-5-23-16
Roberto Serafinelli, Andrea Marinucci, Alessandra De Rosa +12
MCG-5-23-16 is a Seyfert 1.9 galaxy at redshift z=0.00849. We analyse here the X-ray spectra obtained with XMM-Newton and NuSTAR data, which are the first contemporaneous observati…
The geometry of the hot corona in MCG-05-23-16 constrained by X-ray polarimetry
D. Tagliacozzo, A. Marinucci, F. Ursini +105
We report on the second observation of the radio-quiet active galactic nucleus (AGN) MCG-05-23-16 performed with the Imaging X-ray Polarimetry Explorer (IXPE). The observation star…
