Supermassive Black Hole Winds in X-rays: SUBWAYS IV. Tracing Radio Emission and Unveiling the Role of Winds

E. Amenta, M. Brienza, G. Bruni +30

Most Active Galactic Nuclei (AGN) are Radio Quiet, with radio emission that may arise from star-formation activity, AGN-driven winds, weak jets, and coronal activity. Disentangling…

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, i…

Introducing The SHell misAlignment Detection for straylight Estimation (SHADE) algorithm: the case of XMM-Newton

S. Piscitelli, G. Ponti, M. Civitani +1

When performing X-ray observations with a Wolter-I telescope, the presence of bright off-axis sources can introduce unfocused rays, known as straylight, which contaminate the detec…

25 years of XMM-Newton observations of the Sgr A complex: 3D distribution and internal structure of the clouds

G. Stel, G. Ponti, F. Haardt +1

Sgr A* is currently very faint. However, X-ray radiation reflected by the Sgr A complex, a group of nearby molecular clouds, suggests that it went through one or more periods of hi…

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…

Cosmic hide and seek: the volumetric rate of X-ray quasi-periodic eruptions

R. Arcodia, A. Merloni, J. Buchner +6

Multi-wavelength extragalactic nuclear transients, particularly those detectable as multi-messengers, are among the primary drivers for the next-generation observatories. X-ray qua…
