Recoiling active galactic nuclei (AGNs) can be formed after the merging of two galaxies and their central supermassive black holes. A novel method recently revealed a handful of recoiling AGN candidates. We report on the arcsec-scale radio structure of one of them, 4C 18.47, a prominent radio emitter. We also present its infrared light curve, indicating significant long-term variability.

反冲活动星系核(AGN)可以在两个星系及其中心超大质量黑洞合并后形成。一种新方法最近揭示了少数反冲 AGN 候选者。我们报告了其中一个 4C 18.47 的弧秒级无线电结构,这是一种著名的无线电发射器。我们还展示了它的红外光曲线,表明存在显着的长期变化。
