  1. ULXはIMBHか? Slim disk Anomalous Anomalous Slim disk Standard Standard L~T4 Rin=const. Low state Low state 高橋弘充 牧島研D2 系内BHBと同じ状態をとるのでは? HR diagram of XTE J1550-564 (Kubota & Makishima 2003) 10keV以下だけでは、 Slim disk / Anomalous Standard / Low state の区別がつきにくい! ULXの特徴   スペクトル:MCD / PL L ∝ Tin^2 Slim/Anomalous状態を遷移? Standard状態のものは? NeXTでハードが観測できると IMBHを検証できる

  2. NeXT連続成分の感度 他に20-30keVの放射を検出 できそうなULX(in 杉保D論) • M81 X-6 • IC342 source 1 • source 2 • NGC1313 source A なんとか20 keV • NGC 253 source 1 •  など TeVγ検出 (銀河ハローから?) 全天で最もFluxの高いULX:M81 X-9 (M33 X-8 を除く) ULXの正体の解明は、 HXDでは難しく、 NeXTで初めて可能と なりそうである HXIでULX状態が きちんと決められるだろう
