标题： Two confirmed compact elliptical galaxies in the Antlia cluster

摘要： 我们通过MAGELLAN-MIKE和GEMINI-GMOS光谱确认了Antlia星系团中心区域存在两个紧凑椭圆（cE）星系。 目前在100 Mpc的距离内，已知的这种稀有类型的星系仅有约十几个。 通过这一发现，Antlia成为最近的星系团，其星系群体中拥有超过一个cE星系。 其中一个星系显示出与该区域占主导地位的巨型椭圆星系相互作用的证据。 显示英文摘要

摘要： We confirm the existence of two compact elliptical (cE) galaxies in the central region of the Antlia cluster through MAGELLAN-MIKE and GEMINI-GMOS spectra. Only about a dozen galaxies of this rare type are known today up to a distance of 100 Mpc. With this finding, Antlia becomes the nearest galaxy cluster harbouring more than one cE galaxy among its galaxy population. One of these galaxies shows evidence of interaction with one of the giant ellipticals that dominate the central region of the cluster.
