  1. What does mean neighbours ? • At the same epoch • simultaneous (transient phenomenae) • before (can affect the SIMBOL-X observing plan) • after (can complement SIMBOL-X observations) • In the same energy range • competition ! • complementary (if performance differs) • In relevant energy range (scientific complementary: e.g. radio, gamma-rays)

  2. SIMBOL-X neighbourhood

  3. Current X-ray observatories After ? Next ASM ? Swift ? (no short term technical limit) Suzaku: 3 years ? ( 2008) ? Chandra ? RXTE until ? XMM (and INTEGRAL)  > 2012 ?

  4. INTEGRAL (2002 - ?) • SIMBOL-X  INTEGRAL source localisation / identification • INTEGRAL  SIMBOL-X observing plan: ISGRI catalog >20 keV flux (or upper limit)

  5. MAXI (Japan, 2008 ?)All sky monitor (ISS)

  6. Two types of X-ray detectors viewing the sky through slit apertures: • GSC: 12 proportional gas counters (2-30 keV). Effective area of 6000 cm² • SSC: CCD camera, 32 CCD chips. Energy resolution: 135 eV FWHM at 5.9keV

  7. NEXT (Japan)

  8. NEXT • Hard X-ray Telescopes (HXTs): use super mirrors to concentrate hard X-rays up to ~80 keV. • Wide-band X-ray Imagers (WXI): • upper-stage soft X-ray detector: thinned X-ray CCDs • lower-stage hard X-ray detector: CdTe pixel detector • Soft Gamma-ray detector (SGD): ultra-low background, high-sensitivity detector in soft gamma-ray band by combining an active shield and a pixel detector. • Soft X-ray Telescope (SXT) and Soft X-ray Spectrometer (SXS). TES (Transition-Edge Sensor) micro-calorimeters (goal 1000 pixels) • Launch 2013 • Duration: 5 years

  9. SRG(Lobster/Rosita)free-flyerlaunch 2011 ? • eRosita (0.5 - 10 keV): All sky survey (~ROSAT) PSF < 20", FOV 41' • LOBSTER (0.1 - 4 keV)  transients • ART XC (5 - 80 keV) Kumakhov optics ? (fiber lens) or coded mask

  10. Astrosat Payload launch 2008 ?

  11. HXMT (China) • The Hard X-ray Modulation Telescope (HXMT): collimated hard X-ray (20-200 keV) telescope all-sky hard X-ray survey • HXMT is based on the direct demodulation (DD) method • NaI(Ti)/CsI(Na) phoswich • The Phase A study: all the key technical difficulties of the telescope have been overcome • Ground prototype of HXMT has been constructed, and the balloon borne flight testing has been finished. • Platform: "Ziyuan II" (Earth Resource II) satellite series. • Launch: 2010 • Mission duration ? • Angular resolution ? • FOV ?

  12. GLAST • 2007 - ? • All Sky Monitor • Should be a major player • Well calibrated at the Simbol-X time (overlap with HESS2, MAGIC 2) • Will most likely produced a huge catalog of unidentified sources (~1 degree error boxes). Identification will be a challenge.

  13. Cerenkov telescopes • Southern hemisphere: HESS • Northern hemisphere: MAGIC, VERITAS • Energy range: ~ 500 GeV – 50 TeV • Angular resolution: ~ 10' • FOV: 5° • Sensitivity: 10 mCrab (1 day) • Will help the identification of the GLAST sources

  14. HESS-2 • Operational next year Virtual

  15. MAGIC II(2007)

  16. The future: CTA • Large telescope arrays • Dense telescope arrays • Large mirror area • Large field of view • Advanced photon detectors • Advance signal & trigger processing slide from W. Hofmann Not to scale !

  17. The future: CTA GLAST Crab E.F(>E) [TeV/cm2s] 10% Crab MAGIC H.E.S.S. 1% Crab slide from W. Hofmann

  18. LOFAR(from 2007)RADIO (30-150 MHz) • All Sky Monitor: transients detection  alert for SIMBOL-X TOOs (e.g. AGNs, μ-quasars) • Well adapted to map extended sources • Clusters: • radiosynch  Lowfar • IC  SIMBOL-X • SNRs: • radiosynch  Lowfar, SIMBOL-X • IC  CTA (HESS, MAGIC)
