Abell 2147<\/b>\u00a0is a\u00a0galaxy cluster<\/a>\u00a0in the\u00a0Abell catalogue<\/a>.[<\/span>3]<\/span><\/span><\/a><\/sup>\u00a0It is located within the core of the\u00a0Hercules Superclusters<\/a>\u00a0(SCI 160), within\u00a0Serpens Caput<\/a>, near the cluster\u00a0Abell 2152<\/a>, approximately two degrees south southwest of the\u00a0Hercules Cluster<\/a>\u00a0(Abell 2151). It is possible that Abell 2147 is actually part of the Hercules Cluster considering that it shares the same redshift of 550 million light years.[<\/span>4]<\/span><\/span><\/a><\/sup>[<\/span>5]<\/span><\/span><\/a><\/sup><\/p>\n

This galaxy cluster contains mostly faint, small and scattered galaxies.[<\/span>4]<\/span><\/span><\/a><\/sup><\/p>\n

Abell 2152<\/b>\u00a0is a bimodal[<\/span>3]<\/span><\/span><\/a><\/sup>\u00a0galaxy cluster and one of three clusters comprising the\u00a0Hercules Supercluster<\/a>. It contains 3\u00a0BCGs<\/a>; the S0 lenticular UGC 10204, the pair UGC 10187, and the SA0 unbarred lenticular CGCG 108-083.[<\/span>2]<\/span><\/span><\/a><\/sup>\u00a0In total there are 41 galaxies which are confirmed to be members of the cluster.[<\/span>1]<\/span><\/span><\/a><\/sup>\u00a0The cluster is classified as a\u00a0Bautz-Morgan<\/a>\u00a0type III and Rood-Sastry class F cluster, indicating morphological irregularity and perhaps dynamical youth.[<\/span>4]<\/span><\/span><\/a><\/sup>\u00a0It is receding from the\u00a0Milky Way<\/a>\u00a0galaxy with a velocity of 12385\u00a0<\/span>km\/s.[<\/span>2]<\/span><\/span><\/a><\/sup><\/p>\n

Abell 2152 is the nearest cluster in which significant\u00a0gravitational lensing<\/a>\u00a0of a background source has been observed. The arc-like background galaxy, known as J160529.52+162633.9, lies at a\u00a0redshift<\/a>\u00a0z=0.1423 and has been magnified by a factor ~1.9 due to the lensing effect.[<\/span>5]<\/span><\/span><\/a><\/sup><\/p>\n<\/div><\/div><\/div>
