AGILE detection of gamma-ray sources coincident with cosmic neutrino events
F. Lucarelli, M. Tavani, G. Piano +34
The origin of cosmic neutrinos is still largely unknown. Using data obtained by the gamma-ray imager on board of the AGILE satellite, we systematically searched for transient gamma…
AGILE, Fermi, Swift, and GASP-WEBT multi-wavelength observations of the high-redshift blazar 4C 71.07 in outburst
S. Vercellone, P. Romano, G. Piano +56
The flat-spectrum radio quasar 4C 71.07 is a high-redshift (), -loud blazar whose optical emission is dominated by the thermal radiation from accretion disc. 4C 7…
Magnetic shielding of soft protons in future X-ray telescopes: the case of the ATHENA Wide Field Imager
Valentina Fioretti, Andrea Bulgarelli, Silvano Molendi +10
Both the interplanetary space and the Earth magnetosphere are populated by low energy ( keV) protons that are potentially able to scatter on the reflecting surface of Wolt…
Simulating Modulated X-ray calibration Sources for future X-ray missions, using GEANT4
C. P. de Vries, V. Fioretti, J. W. den Herder +2
The XIFU X-ray spectrometer instrument on the future Athena mission needs X-ray calibration sources to calibrate the gains of the individual detector pixels. For this purpose, elec…
The Geant4 mass model of the ATHENA Silicon Pore Optics and its effect on soft proton scattering
Valentina Fioretti, Andrea Bulgarelli, Simone Lotti +6
Given the unprecedented effective area, the new ATHENA Silicon Pore Optics (SPO) focusing technology, the dynamic and variable L2 environment, where no X-ray mission has flown up t…
Calibration of AGILE-GRID with on-ground data and Monte Carlo simulations
P. W. Cattaneo, A. Rappoldi, A. Argan +41
AGILE is a mission of the Italian Space Agency (ASI) Scientific Program dedicated to gamma-ray astrophysics, operating in a low Earth orbit since April 23, 2007. It is designed to…
