Accretion onto supermassive black holes powers the most luminous persistent sources in the Universe, the so-called active galactic nuclei, whose emission is characterized by two di…
Tracking down the broadband polarimetric properties of PG 1553+113
Riccardo Middei, Svetlana G. Jorstad, Alan P. Marscher +78
We report on a nine-month monitoring campaign of the blazar PG 1553+113, relying on three observations carried out in 2025 with the Imaging X-ray Polarimetry Explorer (IXPE) and su…
Ultra-thick warm absorbers: Enlarging the parameter space of AGN ionised outflows
R. Middei, E. Piconcelli, E. Nardini +9
The analysis of X-ray absorption features in active galactic nuclei (AGN) provides a wealth of information about the physical properties of the matter surrounding supermassive blac…
Active Galactic Nuclei-driven Metallicity Enrichment in the Interstellar Medium of Mrk 573

We present the first spatially resolved at pc scale application of AGN-specific metallicity diagnostics for the nearby Compton-thick Seyfert 2 galaxy Mrk 573 ()…
Winds of Change: XRISM Resolve X-ray spectroscopy of NGC 4051
James Reeves, Shoji Ogawa, Tracey Jane Turner +7
NGC 4051 is a nearby (16.7 Mpc), Narrow Line Seyfert 1 galaxy (NLS1), which has a low black hole mass of M. It is also known for its rapid X-ray variability, on ti…
Fast, dust-poor outflows in the local candidate dual AGN MCG-03-34-64 observed with VLT/ERIS
