Cosmic Vision 2020

• Definition of the ESA program for the period
  2015-2025
•   fix on the future science targets of our
  space community  
• set the agenda for key areas of necessary
  technological development  
• Past exercises 1984/5 (Horizon 2000) 1994/5
  (Cosmic Vision 2004-2014)

Cosmic Vision 2020

• Calendar- april 2004 call for themes for
  Cosmic Vision 2020- 1st june 2004 deadline,
  150 proposals received- summer 2004
  definition of themes for Cosmic Vision- 15-16
  september 2004 Cosmic Vision workshop, UNESCO,
  Paris- 19-21 april 2005 ESLAB Symposium,
  ESTEC, Noordwijk- summer 2005 final report-
  end of 2005 (?) first call for mission
  proposals
• Cosmic Vision 2020 themes AWG Other worlds and
  life in the universe The early Universe The
  evolving violent universe FPAG Toward quantum
  gravity Beyond the standard model The
  gravitational wave universe SSWG From the Sun
  to the Earth and beyond Tracing the origin of
  the solar system Life and habitability in the
  solar system and beyond

Cosmic Vision 2020
The input of the gamma-ray community

• Hard X and Gamma-ray Polarization the ultimate
  dimension(E. Caroli)
• MeV Gamma-Ray Science (R. Diehl)
• Exploring the hard X-/gamma-ray continuum sky at
  unprecedented sensitivty (F. Frontera)
• Nuclear astrophysics - Gamma-ray Spectroscopy in
  the MeV Domain (J. Knödlseder)
• Probing the high energy universe (F. Lebrun)
• Gamma Ray Burst polarization (N. Produit)
• Unveiling the High Energy Obscured Universe
  hunting collapsed objects physics (P. Ubertini)

Cosmic Vision Workshop
15-16 september 2004 (UNESCO, Paris)

• Presentation of the 9 themes
• Darwin and XEUS emerge as future
   cornerstone-like  missions for astronomy
  within Cosmic Vision 2020
• The Evolving Violent Universe subjects (C. Done
  presentation)- fundamental interactions
  gravity (e.g. BH)- fundamental interactions
  ultradense matter (e.g. NS)- black holes at high
  z- supernovae and GRBs- nucleosynthesis and
  life cycles of matter
• Requirements of next generation X-ray observatory
  (C. Done)- large area (10 m2)- broad bandpass
  (0.1 - 100 keV)- high spatial resolution (2-5
  arcsec)- high spectral resolution (1-2 eV)-
  fast detectors (µs)- polarimetry

Cosmic Vision Workshop
The high-energy roadmap - the AWG vision
Only X-ray observatory in view !

Cosmic Vision 2020 and gamma-rays
Paris Workshop

• So far, gamma-ray astronomy is almost absent in
  Cosmic Vision 2020- science (C. Done
  presentation)   MeV lines from supernova
  remnants   (i.e. nucleosynthesis)- technology
  (A. Peacock presentation)   gamma-ray
  imager   (i.e. Laue diffraction lens, L2)
• Too many themes ? Too many missions ?
  Coordination ?

ESLAB Symposium

• ESA agreed to give a slot to the European
  gamma-ray community to present their scientific
  prospects
• The ball is now in our field lets play it well
  !!!

8
ESLAB Symposium

• Fundamental Physics from Space- space as
  laboratory for fundamental physics- pioneering
  gravitational wave astronomy with ESA
• Space Astronomy (1)- other worlds and life in
  the Universe- the formation of planets, stars,
  and galaxies
• Space Astronomy (2)- the energetic universe-
  the dark side of the universe
• Solar System (1)- our understanding of the solar
  system now and then- from Sun to Earth and
  beyond the plasma universe
• Solar System (2)- tracing the origin of the
  solar system- life and habitability in the solar
  system and beyond

9
ESLAB Symposium
The Energetic Universe

• The energetic Universe, Barcons (30 min)
• At the frontier of X-ray astronomy, mapping the
  rotating surface of isolated neutron stars,
  Caraveo (20 min)
• Opening a new window to fundamental physics and
  astrophysics X-ray polarimetry, Costa (20 min)
• Prospects in space-based gamma-ray astronomy,
  Knödlseder (20 min)

The objectives for today
Workout the scientific key questions of our field
Convert these scientific key questions into a
mission philosophie
ESLAB symposium presentation

• Science objectives- The Comptonised Universe (A.
  Zdziarski)- Nuclear Astrophysics (R. Diehl)-
  Cosmic accelerators (G. Kanbach)
• Mission concepts- Coded mask telescope for
  gamma-rays (P. Ubertini)- Polarisation
  measurements (E. Caroli)- Laue lens for hard
  X-rays (F. Frontera)- Laue lens for gamma-rays
  (P. von Ballmoos)- Compton-pair telescope (G.
  Kanbach)
