论文摘要
在光学图像中，未充分研究的孤立相互作用的星系对KPG 486（NGC 6090）显示出与触角（NGC 4038/39）的星系对相似的特征。为了比较两个星系对之间的离子化氢气，形态和运动学和动态行为的分布，我们在NGC 6090的H $α$发射线中进行了观察，并用扫描Fabry-Perot干涉仪PUMA获得了扫描的NGC 6090。对于NGC 6090中的每个星系，我们获得了几个运动学参数，其速度场及其旋转曲线，我们还分析了它们相遇引起的一些扰动。我们通过将结果与文献的运动结果进行比较来验证结果的一致性。我们在NGC 6090上的结果与先前针对触角的类似运动学分析获得的结果的比较突出了这些星系对之间的巨大差异。
In optical images, the not amply studied isolated interacting galaxy pair KPG 486 (NGC 6090) displays similar features to the galaxy pair The Antennae (NGC 4038/39). To compare the distribution of ionized hydrogen gas, morphology and kinematic and dynamic behaviour between both galaxy pairs, we present observations in the H$α$ emission line of NGC 6090 acquired with the scanning Fabry-Perot interferometer, PUMA. For each galaxy in NGC 6090 we obtained several kinematic parameters, its velocity field and its rotation curve, we also analysed some of the perturbations induced by their encounter. We verified the consistency of our results by comparing them with kinematic results from the literature. The comparison of our results on NGC 6090 with those obtained in a previous similar kinematic analysis made for The Antennae highlighted great differences between these galaxy pairs.
