We present an extension of our previous research on the early-type galaxy population of the Antlia cluster (d ~ 35 Mpc), achieving a total coverage of ~ 2.6 deg x deg and performing surface photometry for ~300 galaxies, 130 of which are new uncatalogued ones. Such new galaxies mainly fall in the low surface brightness (LSB) regime, but there are also some lenticulars (S0) which support the existence of unique functions that connect bright and dwarf galaxies in the scaling relations. We analyse the projected spatial distribution of galaxies up to a distance of ~800 kpc from NGC 3268, the adopted centre, as well as the radial velocity distribution and the correlation between galaxy colour and effective radius with the projected spatial distribution. We also obtain the luminosity function of the early-type galaxies and the distribution of stellar masses using the T1-band magnitudes and adopted mass-luminosity ratios. Additionally, we correlate the central galaxy distribution with an X-ray emission map from the literature. Based on the analysis of the radial velocities and galaxy colour distributions, we find that galaxies redder than the colour-magnitude relation (CMR) have a velocity distribution strongly concentrated towards the values of the dominant galaxies and are homogeneously distributed throughout the cluster. Those bluer than the CMR, in turn, have a much more extended radial velocity distribution and are concentrated towards the centre of the cluster. We also identify 12 candidates to ultra diffuse galaxies (UDG), that seem to be split into two families, and speculate about their origins in the context of the cluster structure.

Antlia 星团中的早型星系：全球属性

我们展示了我们之前对 Antlia 星团（d ~ 35 Mpc）的早期类型星系群的研究的扩展，实现了 ~ 2.6 度 x 度的总覆盖范围，并对 ~300 个星系进行了表面光度测量，其中 130 个是新的未分类的。这样的新星系主要落在低表面亮度（LSB）区域，但也有一些柱状透镜（S0）支持在尺度关系中连接亮星系和矮星系的独特功能的存在。我们分析了距离 NGC 3268（采用的中心）约 800 kpc 的星系的投影空间分布，以及径向速度分布以及星系颜色和有效半径与投影空间分布之间的相关性。我们还使用 T1 波段的星等和采用的质光比获得了早型星系的光度函数和恒星质量的分布。此外，我们将中央星系分布与文献中的 X 射线发射图相关联。基于对径向速度和星系颜色分布的分析，我们发现比颜色-星等关系（CMR）更红的星系的速度分布强烈地集中在主导星系的值上，并且在整个星团中均匀分布。反过来，比 CMR 更蓝的那些具有更广泛的径向速度分布，并且集中在星团的中心。我们还确定了 12 个超扩散星系 (UDG) 的候选者，它们似乎分为两个家族，
