Unveiling the dynamics of the ultra-fast outflow in IRAS 13224-3809 with X-ray spectroscopy

Pierpaolo Condò, Francesco Tombesi, Marco Laurenti +9

IRAS 13224-3809 is one of the most intensively studied narrow-line Seyfert 1 galaxies, with a rich literature reporting diverse and sometimes contrasting interpretations of its com…

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…

XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region

E. Kammoun, T. Kawamuro, K. Murakami +48

We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…

Emission and Absorption Features of Magnetically Driven Disk Winds in Black Hole X-Ray Binaries

Atsushi Tanimoto, Keigo Fukumura, Shoji Ogawa +5

We investigate accretion disk winds commonly observed in galactic black hole (BH) X-ray binaries (XRB), which manifest as blueshifted absorption features in X-ray spectra. We model…

Fermi-LAT Discovery of a Gamma-ray Outburst from the Peculiar Compact Steep Spectrum Radiogalaxy 3C 216

Federica Giacchino, Giovanni La Mura, Stefano Ciprini +3

3C 216 is an extragalactic radio source classified as a compact steep spectrum (CSS) object, associated with the source 4FGL J0910.0+4257 detected by the Large Area Telescope (LAT)…

X-ray polarization measurement of the gold standard of radio-quiet active galactic nuclei : NGC 1068

F. Marin, A. Marinucci, M. Laurenti +102

We used the Imaging X-ray Polarimetry Explorer (IXPE) satellite to measure, for the first time, the 2-8 keV polarization of NGC 1068. We pointed IXPE for a net exposure time of 1.1…

Detection of X-ray Polarization from the Blazar 1ES 1959+650 with the Imaging X-ray Polarimetry Explorer

Manel Errando, Ioannis Liodakis, Alan P. Marscher +142

Observations of linear polarization in the 2-8 keV energy range with the Imaging X-ray Polarimetry Explorer (IXPE) explore the magnetic field geometry and dynamics of the regions g…

Observations of Low and Intermediate Spectral Peak Blazars with the Imaging X-ray Polarimetry Explorer

Herman L. Marshall, Ioannis Liodakis, Alan P. Marscher +145

We present X-ray polarimetry observations from the Imaging X-ray Polarimetry Explorer (IXPE) of three low spectral peak and one intermediate spectral peak blazars, namely 3C 273, 3…

IXPE and multi-wavelength observations of blazar PG 1553+113 reveal an orphan optical polarization swing

Riccardo Middei, Matteo Perri, Simonetta Puccetti +119

The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consen…

Rapid Variability of the accretion disk wind in the narrow line Seyfert 1, PG 1448+273

James Reeves, Valentina Braito, Delphine Porquet +3

PG 1448+273 is a luminous, nearby (), narrow line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. XMM-Newton observations of PG 1448+273 in 2017 rev…
