Título:“The Hot and Energetic Universe with Athena.”


Resumen:In this talk I will present the scientific objectives and design 
status of Athena - the Advanced Telescope for High-ENergy Astrophysics. 
Athena was selected in June 2014 as the second L-class mission in ESA's 
Cosmic Vision 2015-25 plan, with a launch foreseen in early 2030s. It is 
an X-ray observatory designed to address the two questions of Cosmic 
Vision science theme 'The Hot and Energetic Universe': a) How does 
ordinary matter assemble into the large-scale structures we see today? 
and; b) How do black holes grow and shape the Universe? It will achieve 
these goals by studying a wide range of astrophysical phenomena: the 
formation and evolution of groups and clusters of galaxies; the chemical 
evolution of hot baryons; feedback effects of active galactic nuclei; 
missing baryons thought to populate the intergalactic medium; the 
formation and early growth of black holes; and the accretion by 
super-massive black holes through cosmic time, among others. These goals 
will be achieved through an unprecedented combination of an X-ray 
telescope with a focal length of 12 m and an effective area of ≥1.4 
square meters at 1 keV, and two instruments: an X-ray Integral Field 
Unit (X-IFU) for spatially-resolved, high spectral resolution (~2.5 eV) 
imaging spectroscopy over a ~5'x5' field-of-view, and a Wide Field 
Imager (WFI) for high count rate, moderate resolution spectroscopy over 
a large field of view (~40'x40'). The mission is currently in the study 
phase ("Phase A") aiming at the scientifically optimal design. Upon 
completion, Athena will be proposed for 'adoption' in 2021, thus leading 
to the start of the construction phase.
