Forgotten treasures in the HST/FOC UV imaging polarimetric archives of active galactic nuclei. IV. 5 Orphaned AGNs
Thibault Barnouin, Frédéric Marin, Enrique Lopez-Rodriguez
The Faint Object Camera (FOC) on board the Hubble Space Telescope (HST) acquired high-resolution spatially resolved polarimetric images of nearby active galactic nuclei (AGNs) in t…
Forgotten treasures in the HST/FOC UV imaging polarimetric archives of active galactic nuclei. II. Mrk 463E
Thibault Barnouin, Frédéric Marin, Enrique Lopez-Rodriguez
The Mrk 463 system is known to host two powerful sources separated by about 4 kpc, both identified as active galactic nuclei (AGN). This makes the Mrk 463 system a unique laborator…
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…
Forgotten treasures in the HST/FOC UV imaging polarimetric archives of active galactic nuclei III. Five years monitoring of M87
F. Marin, T. Barnouin, K. Wu +1
The active galactic nucleus (AGN) within M87, a giant elliptical galaxy, is responsible for one of the closest kiloparsec-scale relativistic jet to Earth. We unearthed unpublished…
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…
