A Song of Lines and Winds: Tracing the Signatures of AGN Outflows in X-rays
M. Laurenti, F. Tombesi, P. Condò +14
Ultra-fast outflows (UFOs) are highly ionized, mildly relativistic winds seen in the X-ray spectra of active galactic nuclei (AGN) and are thought to contribute to AGN feedback and…

Unveiling the origin of XMM-Newton soft proton flares II. Systematics in the proton spectral analysis
T. Mineo, V. Fioretti, S. Lotti +7
Low-energy protons entering the field of view of the XMM-Newton telescope scatter with the X-ray mirror surface and might reach the X-ray detectors on the focal plane. They manifes…

Unveiling the origin of XMM-Newton soft proton flares: I. Design and validation of a response matrix for proton spectral analysis
Valentina Fioretti, Teresa Mineo, Simone Lotti +8
Low-energy (<300 keV) protons entering the field of view of XMM-Newton are observed in the form of a sudden increase in the background level, the so-called soft proton flares, affe…
