论文摘要
敏感（噪声$ \ sim 16 \，μ$ \ jyb），高分辨率（$ \ sim 10'' $）Meerkat对Fornax的观察表明，其巨大的裂片具有双壳形态，在中央广播Jets中嵌入了较差的和延伸的茧，同时将其嵌入了中央广播Jets的范围内，同时又构成了insed insed insed insed insed ins of ins in nounce ins in nounce ins in nounce ins in nounce ins in nounce ins in nounce ins in nounce ins in nounce ins in nounce insed Galaxy。 Fornax A的叶和喷气机的光谱无线电特性表明其核活动正在迅速闪烁。核活动的多个发作一定已经形成了无线电湖，最后停止了$ 12 $ MYR。最近（$ \ sim 3 $ Myr Ago），这是一个核活动的功能较小，短（$ \ Lessim 1 $ Myr）阶段产生了中央喷气机。中心中中性和分子气体的分布和运动学对复发性核活动与周围星际培养基之间的相互作用有见解。
Sensitive (noise $\sim 16\,μ$\Jyb), high-resolution ($\sim 10''$) MeerKAT observations of Fornax A show that its giant lobes have a double-shell morphology, where dense filaments are embedded in a diffuse and extended cocoon, while the central radio jets are confined within the host galaxy. The spectral radio properties of the lobes and jets of Fornax A reveal that its nuclear activity is rapidly flickering. Multiple episodes of nuclear activity must have formed the radio lobes, for which the last stopped $12$ Myr ago. More recently ($\sim 3$ Myr ago), a less powerful and short ($\lesssim 1$ Myr) phase of nuclear activity generated the central jets. The distribution and kinematics of the neutral and molecular gas in the centre give insights on the interaction between the recurrent nuclear activity and the surrounding interstellar medium.
