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…
The Athena X-ray Integral Field Unit
Didier Barret, Thien Lam Trong, Jan-Willem den Herder +100
The X-ray Integral Field Unit (X-IFU) is the high resolution X-ray spectrometer of the ESA Athena X-ray observatory. Over a field of view of 5' equivalent diameter, it will deliver…
AGN with discordant optical and X-ray classification are not a physical family: Diverse origin in two AGN
I. Ordovás-Pascual, S. Mateos, F. J. Carrera +7
Approximately 3-17 percent of Active Galactic Nuclei (AGN) without detected rest-frame UV/optical broad emission lines (type-2 AGN) do not show absorption in X-rays. The physical o…
The NuSTAR view of the true Type 2 Seyfert NGC3147
Stefano Bianchi, Andrea Marinucci, Giorgio Matt +6
We present the first NuSTAR observation of a 'true' Type 2 Seyfert galaxy. The 3-40 keV X-ray spectrum of NGC3147 is characterised by a simple power-law, with a standard Γ~1.7 and…
The Athena X-ray Integral Field Unit (X-IFU)
Didier Barret, Thien Lam Trong, Jan-Willem den Herder +88
The X-ray Integral Field Unit (X-IFU) on board the Advanced Telescope for High-ENergy Astrophysics (Athena) will provide spatially resolved high-resolution X-ray spectroscopy from…
X-ray absorption, nuclear infrared emission and dust covering factors of AGN: testing Unification Schemes
S. Mateos, F. J. Carrera, A. Alonso-Herrero +9
We present the distributions of geometrical covering factors of active galactic nuclei (AGNs) dusty tori (f2) using an X-ray selected complete sample of 227 AGN drawn from the Brig…
