1 田代 信(埼玉大)とAGN/jetの仲間たち Tashiro, M. (Saitama Univ.)
0.1Gyr AGN activity 田代 信(埼玉大)とAGN/jetの仲間たち Tashiro, M. (Saitama Univ.) Time

2 Who knows the energy balance ?
Input SMBH形成史 ICMの動向  基本的には、 LdM/dtを推定

3 Who knows the energy balance ?
Output Radiation Accretion disk Jet Lobe Kinetic energy ? CXO ASCA,… ?? Output = h Input; h=?

4 What is the AGN like ? RQAGN: LT ~ 1E42~45 erg/s RLAGN: L=LT+LNT
~ 1E44~48 (d-4) erg/s : d = beaming factor = 1~10 LNT ~ LT ??

5 Inverse-Compton X-rays from radio lobes (terminal of the outflow)
Centaurus B : Newton Fornax A : with ASCA 2分角 Pictor A Chandra NGC 612, 4C 73.08, PSK 一方、Jetの観測はCMB/ICとSSCの区別が難しい

Electron energies stored in radio lobes © 磯部D論 Isobe, N., 2002 Ph. D. thesis LX(2-10keV) [1040 erg s-1] Lkin [(1+k) 1040 erg s-1] 10 mG 1 mG 100 mG ue = 10 um が典型的 synchrotron radio vs. IC-X → energy densities of magnetic fields and electrons Energetics: Lkin Tcool~ueV +umV  derives…… Lkin~ Lx ge = 10 3 – 10 5 だった? AGN jetは銀河間空間の重要なエネルギー供給源

7 Distant Lobes LIC ∝ uCMB∝(1+z)4 FIC ∝(1+z)2 すなわち SB ∝(1+z)4 !
AGNの運動エネルギー放出の歴史書 問題はサイズ、と電波観測。。。

8 What we have observed with nonthermal photons are….
Energy cut off?? © Makishima, Takahashi

9 ASTRO-E2 HXD to NeXT HXI/SGD
extended sources Lobes: HXI covers ge=103 – 104 corresponding to the synchrotron radio Bright Lobes 3C 3C 3C 3C 3C 3C 3C 3C 3C 4C …… どれくらい候補があるのか? z > 0.3 サイズ > 120 arcsec 一応 Cluster 中にない。
