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

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)
