论文摘要
无线电源3C 223.1（J094124.028+394441.95）的最新LOFAR 144 MHz图的比较与我们基于档案数据建立的VLA映射与VLA地图的比较，并根据档案数据建立了8.3 GHz，确定了这个X形宽度宽度（XRG），是一个X型宽度镜头。裂片。其异常光谱梯度的细节在这里以前所未有的精度揭示。我们还强调了该XRG的“双回旋镖”型无线电形态。显而易见的是，该XRG中的特殊频谱梯度归因于与同步质等离子体在其两个主要裂片中流式传输的粒子加速度相关的，因为它们会撞击并遇到Elliptical Galaxy Host Hots Host Hots Thit Xrg的巨大粉尘中的磁性张力。我们还提请人们注意XRG之间有趣的新形态学特征，即在两个主要无线电叶的（平行）轴（平行）轴之间观察到侧向偏移。
A comparison of the recent LOFAR 144 MHz map of the radio source 3C 223.1 (J094124.028+394441.95) with the VLA maps at 4.9 GHz and 8.3 GHz that we built based on archival data, establishes this X-shaped radio galaxy (XRG) as a singularly robust case where the 'wings' exhibit a distinctly flatter radio spectrum than the primary lobes. The details of its anomalous spectral gradient are unravelled here with unprecedented precision. We also highlight the 'double boomerang' type radio morphology of this XRG. It appears plausible that the peculiar spectral gradient in this XRG is owed to particle acceleration associated with the rebounding of the collimated backflows of synchrotron plasma streaming through its two primary lobes, as they impinge upon and encounter the magnetic tension in the prominent dusty disk of the elliptical galaxy hosting this XRG. We also draw attention to an intriguing new morphological peculiarity among XRGs, namely, a lateral offset observed between the (parallel) axes of the two primary radio lobes.
