1. Cross-wavelength synergy: VSOP-2 & CTA projects M. Kino (NAOJ) On behalf of VSOP-2 Science Working Group 「高エネルギー宇宙物理学の将来と CTA 」 2010 Jan 9 th,@ 宇宙線研

2. Why VSOP-2 & CTA? M87 (VERITAS, VLBA 43GHz, HESS, MAGIC collaboration 2009) 提案： 「 VSOP-2&CTA 同時観測」を是非やりませんか？ 日本主導の「ユニークな科学成果」が期待できる （後述）。 R~δct VSOP-2 人類史上最高の空間分解能

3. Outline Looking back the AGN-science history in terms of “Radio” & “VHE” collaboration. 2000 ~ VLA - Chandra Era ~ arcsec world 2008 ~ VLBI - Fermi Era ~ mas world 201? ~ VSOP-2- CTA ~ 0.1 mas world D Angular Resolution ∝ λ(wavelength)/ D(baseline)

4. VLA & Chandra era: (2000~) Comparable angular Resolution ≲ 1 arcsec VLA (Radio) Chandra (X-ray)

5. External Shock World Forward-Shocks & Reverse-Shocks Centaurus A Cygnus A Yaji+ Kraft+

6. What we have learned U NT e /U B ~1-100 (e.g., Tashiro+, Croston+, Hardcastle+, Kataoka+ Isobe+,Yaji+) “invisible” power (thermal e, proton) (e.g., MK+, Birzan+, Ito+ ) Particle dominance for large ( ≳ 10kpc) jets. Isobe+08 U NT e /U B ~1 U NT e /U B ~100 U NT e UBUB

7. Long term monitor of blazar motions by VLBA 15 GHz. MOJAVE (Monitoring Of Jets in AGN with VLBA Experiments) http://www.physics.purdue.edu/~mlister/MOJAVE/index.html VLBI-Fermi Era: (2008~) VLBA (Radio) MOJAVE survey 空間分解した多数イメージに よって初めて分かる

8. AGN sky: MOJAVE/Fermi view MOJAVE/Fermi blazar studies (Lister+, Kovalev+, …). MOJAVE/Fermi/CTA will lead to statistical studies of blazars. CTA together with VSOP-2 KSPs?

9. ひとこと補足 : KSP = Key Science Program VLBI 分野以外の多波長、理論の方々 のご参加も大歓迎いたします。 公募制です 。
