The Wide Field Imager (WFI) is one of two instruments for the Advanced Telescope for High-ENergy Astrophysics (Athena). In this paper we summarise three of the many key science objectives for the WFI { the formation and growth of supermassive black holes, non-gravitational heating in clusters of galaxies, and spin measurements of stellar mass black holes { and describe their translation into the science requirements and ultimately instrument requirements. The WFI will be designed to provide… 

The Wide Field Imager instrument for Athena

ESA’s next large X-ray mission ATHENA is designed to address the Cosmic Vision science theme 'The Hot and Energetic Universe'. It will provide answers to the two key astrophysical questions how does

Thermal analysis of the WFI on the ATHENA observatory

The WFI (Wide-Field Imager) instrument is one of two instruments of the ATHENA (Advanced Telescope for High- ENergy Astrophysics) mission. ATHENA is the second L-class mission in ESA’s Cosmic Vision

The wide field imager instrument for Athena

The WFI (Wide Field Imager) instrument is planned to be one of two complementary focal plane cameras on ESA’s next X-ray observatory Athena. It combines unprecedented survey power through its large

Evaluation of the ATHENA/WFI instrumental background

An estimate of the WFI instrumental background for a proposed combination of design optimization and background rejection algorithm is given, showing that WFI is compliant with science background requirements.

White dwarfs, neutron stars and stellar mass black holes are key laboratories to study matter in most extreme conditions of gravity and magnetic field. The unprecedented effective area of Athena+

Statistics of relativistically broadened Fe Kα lines in AGN

We present preliminary results on the properties of relativistically broadened Fe Kα lines in a collection of more then 100 Active Galactic Nuclei (AGN) observed by the XMM-Newton EPIC-pn camera. Our

The Hot and Energetic Universe: The formation and growth of the earliest supermassive black holes

A crucial challenge in astrophysics over the coming decades will be to understand the origins of supermassive black holes (SMBHs) that lie at the centres of most, if not all, galaxies. The processes

Jet-Launching Structure Resolved Near the Supermassive Black Hole in M87

Radio interferometry observations of the elliptical galaxy M87 are reported that spatially resolve the base of the jet in this source, suggesting that the M87 jet is powered by an accretion disk in a prograde orbit around a spinning black hole.

The X-ray/SZ view of the virial region - I. Thermodynamic properties

We measure the thermodynamic properties of cluster outer regions to provide constraints on the processes that rule the formation of large scale structures. We derived the thermodynamic properties of

The Hot and Energetic Universe: The astrophysics of galaxy groups and clusters

As the nodes of the cosmic web, clusters of galaxies trace the large-scale distribution of matter in the Universe. They are thus privileged sites in which to investigate the complex physics of
