  2. Outline of the talk Only some of planned/designed/studied X-ray Observatories will be introduced… • The KeV – TeV Connection: a few reasons of the “science case” (not exhaustive) • A golden age for X-ray astronomy • eRosita • Simbol X • The Others (MIRAX, HXMT, NEXT, EXIST…) (not exhaustive) • Considerations Towards A CTA FP7 Design Study

  3. X-ray observation tracing the synchrotron emission of relativistic electrons are well suited to the identification of VHE Gamma Ray emitters Identification of Sources (Funk et al., astro-ph/0609586) Association is certainly spatial/morphology coincidence… • Hess ~2’(Aharonian et al., 2006) • ASCA AX J1813-178, highly absorbed, Hard (~1.8), extended • INTEGRAL IGRJ18135-1751 (Ubertini et al., 2006), softer than ASCA • Swift-XRT (Landi 2006), hard source, highly absorbed • VLA 20 and 90 cm young (~ 1ky) shell like SNR2.5’ diameter (G12.82-0.02) coincident with HESS (Brogan 2005) • XMM spectral and morphological studies, (Funk et al. 2006),compact core, extended tail, non thermal, highly absorbed Towards A CTA FP7 Design Study

  4. Identification of Sources (2) (Funk et al., astro-ph/0611646) It’s the positional and morphological coincidence that allows identification XMM-Newton map around HESS J1813-178 • Compact X- ray core • Extended with a hard tail toward North-East • Embedded in the radio shell type SNR G12.82-0.02 • Hard Spectrum Pulsar Wind Nebula, Composite SNR, even if ….

  6. A multimavelength coherent picture (Aharonian et al., astro-ph/0611813) Identification, that is understanding, implies that a coherent multiwavelength scenario must emerge See also RX J0852.0-4622 • Contours are from ASCA (1-3 keV band) • Correlation is amazing • A single electron population generates both the X (Sync.) and the Gamma (IC) radiation • Particle acceleration up to 100 TeV is required • Model interpretation is not so easy (Lemoine et al., 2006) HESS map of RX J1713.7-3946 Towards A CTA FP7 Design Study
