Time-evolving Diagnostic of the Ionized Absorbers in NGC 4051. II. High-throughput Time-resolved Spectroscopy
Alfredo Luminari, Fabrizio Nicastro, Roberto Serafinelli +5
Active Galactic Nuclei (AGNs) are one of the most powerful sources in the Universe. The accretion-liberated energy can strongly impact the surrounding environment, up to the host g…
Testing the Correlations between X-ray Spectral Properties and Polarization for High Synchrotron Peaked Blazars
M. Lynne Saade, Steven Ehlert, Ioannis Liodakis +4
IXPE has enabled the X-ray polarizations of many blazars to be measured. We perform the first population study for high synchrotron peaked blazars observed using IXPE using a unifo…
Directly tracking the re-brightening of a supermassive black hole accretion disk
R. Middei, E. Nardini, C. Done +12
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…
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,…
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…
Is XRISM/Resolve probing a "raining" absorber in Mrk 509?
M. Dadina, V. Missaglia, V. Braito +19
X-ray spectroscopy of AGN offers unique insights into the reprocessing of radiationand gas dynamics near SMBH. The Sey 1 galaxy Mrk 509 is an ideal laboratory for these studies sin…
