Centaurus Cluster - Wikipedia
The Centaurus Cluster (A3526) is a cluster of hundreds of galaxies, located approximately 170 million light-years away in the Centaurus constellation. The brightest member galaxy is the elliptical galaxy NGC 4696 (~11m). The Centaurus cluster shares its supercluster, the Hydra–Centaurus Supercluster, with IC4329 Cluster and Hydra Cluster.

半人馬座星系團 （A3526）是擁有數百個星系的 星系集團，位於 半人馬座 的方向上，距離一億五千五百萬 光年 遠，最亮的星系是 NGC 4696. （～11等）。 半人馬座星系團與 IC4329星系團 、 長蛇座星系團 共同組成 長蛇-半人馬座超星系團。 這個星系團分成兩個有不同速度的次集團星系 [2]，擁有 NGC 4696 的半人馬座30是主要的次集團。 半人馬座45與半人馬座30的相對速度是1,500公里/秒，並且相信正在被主集團吞噬中。 ^ 1.0 1.1 1.2 1.3 NASA/IPAC Extragalactic …

2016年1月7日 · We examine deep Chandra X-ray observations of the Centaurus cluster of galaxies, Abell 3526. Applying a gradient magnitude filter reveals a wealth of structure, from filamentary soft emission on 100pc (0.5 arcsec) scales close to the nucleus to features 10s of kpc in size at larger radii.
Abell 3526: Centaurus Galaxy Cluster • The X-image, consisting of more than a week of Chandra observing time, reveals several sets of cavities in the hot gas, and a large plume of hot gas extending to the upper left at the 10 o'clock position. • The inner cavities are bright at radio wavelengths, showing

We present results of deep integral-field spectroscopy observations using high-resolution optical (4150–7200 Å) VLT VIsible MultiObject Spectrograph spectra of NGC 4696, the dominant galaxy in the Centaurus cluster (Abell 3526). After the Virgo cluster, this is the second nearest (z= 0.0104) example of a cool-core cluster.
