  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 9th,@宇宙線研

  2. Why VSOP-2 & CTA? M87 (VERITAS, VLBA 43GHz, HESS, MAGIC collaboration 2009) R~δct VSOP-2 人類史上最高の空間分解能 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）。

  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 Angular Resolution ∝ λ(wavelength)/ D(baseline) D

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

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

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

  7. VLBI-Fermi Era: (2008~) VLBA (Radio) MOJAVE survey 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 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 公募制です。 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。

  10. Extremely Young Jet: 3C 84 • Core of perseus cluster • (z=0.0176, i.e., D =77 Mpc) • Mini radio-lobe 3C 84 • t_age = size/ velocity~50 yrs, • size ~5pc (Asada+06) Perseus Cluster (Chandra X-ray) 3C84 (HALCA) Radio core jet 5 pc Radio lobe

  11. GeV/Radio-Core Outburst Abdo+09 COS-B Fermi EGRET UMRAO

  12. Moment of Birth! コアを空間分解し、誕生の瞬間を初検出！ C3 flux’s rising! C3 is the new-born baby! Time (year)

  13. Specifications of VSOP-2

  14. VSOP-2/CTA will see… VERA 22 GHz Resolution of VSOP-2 (22 GHz) reaches ~0.1 pc! VSOP-2/CTA will offer a key to solving the origin of γ-ray. Nagai+ 1 pc CTA may detect TeV γ. Variability is a key. Abdo+09

  15. Towards the central engine: M 87 ここを空間分解

  16. 2008 flare: VHE/VLBI correlation! M87 (VERITAS, VLBA 43GHz, HESS, MAGIC collaboration 2009) 76 Rg 本質は空間分解 Time

  17. VSOP-2/CTA will see… Walker (NRAO) VSOP-2 (43 GHz) will see this ~ 0.0032pc eye! 0.08pc VSOP-2/CTA will show us a hint for the central- engine mechanism. CTA easily detect TeV γ. Variability is a key. Wagner+10

  18. Summary • VLBIは、1ミリ秒角以下の空間分解能を持つ唯 • 一無二の装置です。是非CTA & VSOP-2 KSPs • をやりましょう！ • 3C 84 γ線放射の起源に迫る！ • M 87 　　中心エンジン機構に迫る！
