The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Geant4 simulation of the residual background in the ATHENA Wide Field Imager from protons deflected by the Charged Particle Diverter
Gábor Galgóczi, Jean-Paul Breuer, Valentina Fioretti +11
X-ray telescopes opened up a new window into the high-energy universe. However, the last generation of these telescopes encountered an unexpected problem: their optics focused not…
Athena charged particle diverter simulations: effects of micro-roughness on proton scattering using Geant4
Jean-Paul Breuer, Gábor Galgóczi, Valentina Fioretti +12
The last generation of X-ray focusing telescopes operating outside the Earth's radiation belt discovered that optics were able to focus not only astrophysical X-ray photons, but al…
Scattering efficiencies measurements of soft protons at grazing incidence from an Athena Silicon Pore Optics sample
R. Amato, S. Diebold, A. Guzman +4
Soft protons are a potential threat for X-ray missions using grazing incidence optics, as once focused onto the detectors they can contribute to increase the background and possibl…
Effective pointing of the ASTRI-Horn telescope using the Cherenkov camera with the Variance method
Simone Iovenitti, Giorgia Sironi, Alberto Segreto +2
Cherenkov telescope cameras are not suitable to perform astrometrical pointing calibration since they are not designed to produce images of the sky, but rather to detect nanosecond…
A non-linear mathematical model for the X-ray variability of the microquasar GRS 1515+105 -- III: Low-frequency Quasi Periodic Oscillations
E. Massaro, F. Capitanio, M. Feroci +1
The X-ray emission from the microquasar GRS 1515+105 shows, together with a very complex variability on different time scales, the presence of low-frequency quasi periodic oscillat…
