2MASX J10222849+5006200 also known as PGC 2362940, is a massive Type-cD elliptical galaxy located in the constellation of Ursa Major. With the redshift of 0.15, the galaxy is located 2.4 billion light-years away from Earth.[1] It is the brightest cluster galaxy (BCG) inside the galaxy cluster, Abell 980.

Characteristics[edit]

2MASX J10222849+5006200 is an optically luminous galaxy with an r-band luminosity of L r > 8L*[2] with a powerful radio source.[3] It is a low-excitation radio galaxy with a 1.4 GHz luminosity range between 2 × 1023 and 3 × 1025 W Hz−1[4] featuring a hybrid of both Fanaroff-Riley (FR) I and FR II sources.[5] The galaxy is a red elliptical galaxy, known to have radio-loud active galactic nucleus with an old stellar population dominating at high stellar mass of M > 1010.5-10.8~M⊙,[6] following an fLE_RL ∝ M^{2.5_* power law of 3.[7] It also exhibits a strong, distinguishable core component correlating with its [O III] 5007 Å line emission, suggesting the galaxy's active galactic nucleus is steadily fueled over the bubble-rise time-scales.[8]

Like all giant elliptical galaxies inhabiting the center of such clusters, 2MASX J10222849+5006200 is found to have a central velocity dispersions in the range of α ~ 300–400 km s−1,[9] which is found to have a tight relation between the BCG itself and its parent cluster velocity dispersion.[10][11] The galaxy also has a light profile, over a large range in radius as described by a de Vaucouleurs surface brightness law, μ(r) α r1/4.[12] In addition, 2MASX J10222849+5006200 has an extended envelope of excess light fitted to its inner regions[13] reaching up to several hundreds of kiloparsecs.[14]
