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 >20 keV flux (or upper limit)

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

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 (Japan)

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.

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

Not to scale !

The future: CTA

• Large telescope arrays• Dense telescope arrays• Large mirror area• Large field of view• Advanced photon detectors• Advance signal & trigger processing
