XMM/HST monitoring of the ultra-soft highly accreting Narrow Line Seyfert 1 RBS 1332
R. Middei, S. Barnier, F. G. Saturni +10
Ultra-soft narrow line Seyfert 1 (US-NLSy) are a poorly observed class of active galactic nuclei characterized by significant flux changes and an extreme soft X-ray excess. This pe…
Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows
V. E. Gianolli, S. Bianchi, P-O Petrucci +44
The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…
Compton-Thick AGN in the NuSTAR era VIII: A joint NuSTAR-XMM-Newton monitoring of the changing-look Compton-thick AGN NGC 1358
Stefano Marchesi, Xiurui Zhao, Núria Torres-Albà +18
We present the multi-epoch monitoring with NuSTAR and XMM-Newton of NGC 1358, a nearby Seyfert 2 galaxy whose properties made it a promising candidate X-ray changing look AGN, i.e.…
A broadband X-ray view of the NLSy1 1E 0754.6+392.8
R. Middei, F. Tombesi, F. Vagnetti +8
The soft X-ray band of many active galactic nuclei (AGNs) is affected by obscuration due to partially ionised matter crossing our line of sight. In this context, two past XMM-Newto…
