MCG-02-12-039

MCG-02-12-039 is the dominant galaxy of Abell 496.^[2] It is known to contain a large galactic halo that is found surrounding it with many distant galaxy companions in the background.^[3] It has also been described as a weak emission line galaxy based on a study published in December 2008.^[4] There is also strong presence of extended optical emission by around 10 arcseconds from the central nucleus, mainly made up of hydrogen-alpha and singly ionized nitrogen.^[5] The estimated equivalent age of a single stellar population in the galaxy is around 1.05 ± 0.21 billion years.^[6] In the center of the galaxy, there are three dust lanes that are found to be uncurling in an anticlockwise direction, in a spiral pattern.^[7]

Evidence found the halo of the galaxy is found to display a blue profile per each increasing radius based on a B-V color profile. However, when observed in visual infrared colors, the profile is shown to be more redder.^[8] There is also a presence of an elongated stellar component with gas components also having the same morphology but to a lesser extent. The central nucleus is found to have its parts blueshifted by around 125 kilometer per seconds.^[9]

A study published in 2020 has found the presence of gas filaments in the galaxy. When observed, the gas components are described as stretched suggesting there is a common origin. Moreover, a misalignment is shown between stellar and gas kinematics, hinting interstellar gas is found to be externally accreted.^[10] The central supermassive black hole of the galaxy is estimated to be around 8.78 M_☉.^[11]
