  1. Kirpal Nandra On behalf of The Athena Co-ordination Group Athena+: Revealing the Hot and Energetic Universe

  2. The Hot and Energetic Universe • Where are the hot baryons and how do they evolve? • How do black holes grow and shape the Universe? • The Astrophysics of the Hot and Energetic Universe Black Hole Accretion Feedback Processes Cosmic Web

  3. 1. Where are the hot baryons and how do they evolve? • Reveal and map the first viralised baryonic structures • Wide field X-ray imaging, imaging X-ray spectroscopy • Determine their dynamical, thermal and chemical evolution • Spatially-resolved X-ray spectroscopy, wide field imaging • Complete the census of baryons in the local Universe • High resolution X-ray spectroscopy • Understand the physics of clusters and groups • Imaging X-ray spectroscopy, wide field of view imaging Structure Formation Baryonic Evolution Cosmic Web Cluster Physics

  4. 2. How do black holes grow and influence the Universe? • Reveal the causes and effects of cosmic feedback • Imaging X-ray spectroscopy, high resolution spectroscopy • Understand the physics of accretion onto compact objects • Fast spectral timing, high throughput spectroscopy • Track obscured accretion through the epoch of galaxy • High throughput wide field X-ray imaging, high throughput spectroscopy • Perform a census of black hole growth at high redshift • Deep wide field X-ray imaging XMM-Newton Cosmic Feedback Accretion physics Obscured accretion High z SMBH

  5. 3. The Astrophysics of the Hot and Energetic Universe • Compact Objects • X-ray binaries, neutron star and pulsars, white dwarfs • Stellar Evolution • Young stars, stellar winds, stellar activity, supernovae, GRBs • The Milky Way • Galactic centre, interstellar dust and gas, hot gas halo • Planets and the solar system • Planets, exoplanets, comets, solar wind Neutron Stars Stellar Activity Galactic Centre Charge Exchange

  6. Science Requirements

  7. Notional Athena+ Mission Profile Ariane V launch to L2, 5yr nominal mission Payload Focal plane 12m Fixed Focal Length Wide Field Imager (Si-based DEPFET) X-ray Integral Field Unit (TES calorimeter) Service Module ESA Silicon Pore Optics 5” (3”) resolution Mirror Assembly

  8. ESA L-class process • Cornerstone approach for large missions (as H2000) • Budget ~€0.9bn ESA cost (plus ~€200M ESA MS) • ESA-led, max. ~20% “non-critical” int. contribution OK • Senior Committee to select single science theme for L2 (2028) and single theme for L3 (2034) • L-class call-to-launch assumption: 14 years • Timeline: • May 24th: white papers on science themes, mission concept • September 2-3: Open workshop on science themes • mid-November: Selection of L2 and L3 based on SC/ESA recommendation • L2 mission call in 2014 (L3 in ~2020)
