渦状銀河の磁場は星間ガス雲の形成,宇宙線の閉じ込め,銀河ハローの形成等を通して銀河における星形成,銀河の進化に影響を及ぼす.銀河磁場の増幅・維持機構を扱う「銀河ダイナモ」の理論は星間ガスの運動を仮定して磁場の時間変化を調べる運動学的理論から,磁場が星間ガスの運動に及ぼす影響を考慮した磁気流体ダイナモ理論へと変貌を遂げ,大局的な3次元磁気流体シミュレーションを通して,準周期的な磁場方向の反転と銀河円盤から銀河ハローへの磁束輸送過程等が明らかになりつつある.銀河磁場は高エネルギー電子によるシン...

Loop like molecular structures have been observed in the Galactic center region with NANTEN milli meter telescope (Fukui et al. 2006). They considered that loops are explained in terms of the buoyant rise of magnetic loops due to the Parker instab...
