Galaxy mergers are a mechanism for rapid quenching of star formation. We are studying E+A galaxies (a type of post-starburst galaxy) and how they are impacted by merging. Examining E+A galaxies with companions offers insight into the evolution of E+As and the quenching process. The Y/Dim Collaboration collected a sample of E+A candidate galaxies from the SDSS DR16. Among the E+A candidates that were visually identified as interacting, 14 were spectroscopically confirmed to have companions. Our sample contained 11 pairs of galaxies and two groups of three galaxies. In one of these groups of three, there are two E+A candidates. Nine of these E+A candidates are involved in minor interactions with their companions.

星系合并是恒星形成快速淬灭的一种机制。我们正在研究 E+A 星系（一种后星暴星系）以及它们如何受到合并的影响。与同伴一起检查 E+A 星系可以深入了解 E+As 的演化和猝灭过程。Y/Dim Collaboration 从 SDSS DR16 收集了一个 E+A 候选星系样本。在视觉识别为相互作用的 E+A 候选者中，有 14 个被光谱证实有同伴。我们的样本包含 11 对星系和两组三个星系。在这些三人组中的一组中，有两名 E+A 候选人。这些 E+A 候选人中有九名与他们的同伴有轻微的互动。
