Unveiling supermassive black hole binaries with FUV-to-NIR spectropolarimetry

Frédéric Marin, Julie Biedermann, Thibault Barnouin

In this proceedings, we review the importance and complexity of detecting and characterizing supermassive binary black holes using conventional techniques (spectroscopy, timing, im…

Polarimetric insights into a potential binary supermassive black hole system in Mrk 231

J. Biedermann, F. Marin, T. Barnouin

Markarian 231 (Mrk 231) is one of the brightest ultraluminous infrared galaxies (ULIRGs) known to date. It displays a unique optical-UV spectrum, characterized by a strong and perp…

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 We unearthed unpublished…

Polarimetry of the potential binary supermassive black hole system in J1430+2303

F. Marin, D. Hutsemékers, I. Liodakis +6

The growth of supermassive black holes (SMBHs) through merging has long been predicted but its detection remains elusive. However, a promising target has been discovered in the Sey…

Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE

V. E. Gianolli, D. E. Kim, S. Bianchi +106

We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
