We have spectroscopically identified 600 new E+A galaxies and candidates across 16 fields totaling roughly 480 square degrees in the Sloan Digital Sky Survey. E+A galaxies are post-starburst systems that have undergone a significant burst of star formation within the past 1–2 Gyr and are now fully quenched. They comprise a small population that is key to understanding the transition from star-forming to quiescent galaxies. Our survey focused on four nearby rich clusters of galaxies and their surroundings: Virgo, Coma, Leo, and Hercules. 356 candidates were identified in the clusters, and an additional 244 were identified in control fields or otherwise outside cluster bounds. Understanding the distribution and dynamics of the E+As has the potential to shed light on the evolutionary mechanisms present within nearby cluster environments. In this note, we give a brief overview of our selection processes and locations, and report on ongoing analyses of the sample.

在斯隆数字巡天中，我们通过光谱确定了 600 个新的 E+A 星系和 16 个领域的候选星系，总面积约为 480 平方度。E+A 星系是星暴后系统，在过去的 1-2 Gyr 内经历了一次重大的恒星形成爆发，现在完全熄灭。它们由一小群人组成，这是理解从恒星形成到静止星系的过渡的关键。我们的调查集中在附近四个丰富的星系团及其周围：室女座、彗发、狮子座和大力神座。在集群中确定了 356 名候选者，在控制领域或集群范围之外确定了另外 244 名候选者。了解 E+As 的分布和动态有可能揭示附近星团环境中存在的进化机制。在这篇笔记中，
