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)

INTEGRAL (2002 - ?)

• SIMBOL-X ? INTEGRAL source localisation /
  identification
• INTEGRAL ? SIMBOL-X observing plan ISGRI catalog
  ?gt20 keV flux (or upper limit)

• 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

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

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 ?

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.

14
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
