论文摘要
在日落附近的地球上,太阳可能会施放“ crepulcular射线”,以使地平线附近的云层掩盖了散落在明亮的光线中的光的起源。原则上,AGN应该能够产生相似的影响。使用新的哈勃空间望远镜(HST)近红外和光学观测值,我们表明活跃的Galaxy IC 5063包含从细胞核中延伸至$ \ gtrsim $ 11 kpc的宽径向射线。我们认为,明亮的光线可能是由于活性核从连续发射的尘土散射而产生的,而黑暗的射线是由于核附近阴影引起的,可能是由于扭曲的圆环。我们还考虑了扩展光的替代AGN相关和出色的起源。
On Earth near sunset, the sun may cast "crepuscular rays" such that clouds near the horizon obscure the origin of light scattered in bright rays. In principle, AGN should be able to produce similar effects. Using new Hubble Space Telescope (HST) near-infrared and optical observations, we show that the active galaxy IC 5063 contains broad radial rays extending to $\gtrsim$11 kpc from the nucleus. We argue that the bright rays may arise from dusty scattering of continuum emission from the active nucleus, while the dark rays are due to shadowing near the nucleus, possibly by a warped torus. We also consider alternative AGN-related and stellar origins for the extended light.
