4C +41.26 known as PGC 2174167, is a massive elliptical galaxy of type E[1] located in the constellation of Canes Venatici. Its redshift is 0.228324, estimating the galaxy to be located 3 billion light years away from Earth.[2] It is the brightest cluster galaxy of Abell 1763 (ACO 1763).[3][4]
Characteristics[edit]
4C +41.26 is one of the largest galaxies. Spanning at least 862,300 light-years across in diameter, it is classified as a Type-cD galaxy.[5] Not to mention, the galaxy has a high line-of-sight peculiar velocity reaching up to vpec ~ 650 km s−1. It has an active galactic nucleus, containing a powerful P1.4 ~ 1026 W Hz−1 bended double-lobed radio source, suggesting 4C +41.26 is likely shaped through its relative bulk intracluster medium (ICM) flow caused by one or several galaxy mergers.[6][7] The galaxy is estimated to have span MK = −25.7 to −27.8 mag, with the cluster halo masses of M500 up to 1.7 × 1015 M⊙.[8]
4C +41.26 is part of the rich galaxy cluster[9] with at least 181 identified galaxy members, fitted through the integrated spectral energy distributions (SEDs)[10] utilized with a set of templates built with GRASIL 3d model,[11] by astronomers.[12] The members in the cluster consists of elliptical, spiral, starburst, and poststarburst galaxies.[13] It is suggested according to observations from Spitzler MIPS Data, researchers have found traces of increased starburst activity in filament galaxies inside ACO 1763.[9]
The cluster hosts two galaxy filaments which stretches towards another neighboring galaxy cluster, Abell 1770 (ACO 1770) located ~ 13 Mpc away. The intracluster gas of ACO 1770 is elongated in the same direction, as indicated by its X-ray morphology. As the cluster is fed by the filaments, it causes 4C +41.26 to be displaced from its original location from center of the cluster (0.1 Mpc off the X-ray peak emission) by the subcluster-cluster collisions and pressure of the intracluster gas. This results the galaxy falling towards Abell 1770.[14]
