ESO 541-13

ESO 541-13 is a Type-cD galaxy dominating the center of Abell 133. It is also a radio galaxy, with its source found mainly compact and is separated into four different components of which two of them are associated with the galaxy itself.^[4][5] The source is also classified as having a steep spectrum and has an amorphous appearance. An extension feature is also found south of the radio lobe feature of the source.^[6] There are also detections of radio emission that is mainly confined within the nucleus region by only a few arcseconds.^[7]

Observations made with Chandra X-ray Observatory found there is a tongue of emission described as extending outwards from the galaxy towards the northwest direction where it is found to overlap together with a radio relic, although partly. Evidence also showed the emission is also of thermal type, originating from cool interstellar gas. This is found likely to be produced through Kelvin-Helmholtz instabilities between the cold gas of the galaxy and also the hot intracluster medium.^[4] The central supermassive black hole of the galaxy is estimated to be 3.0 × 10⁹ M_☉.^[8]

Evidence found the galaxy has hydrogen-alpha emission described as extended. The stellar population of the galaxy is mainly made up of two types; stars with an upper limit of around 20 billion years old and very young stars that are less than 100 million years old, with them contributing the light at 20%.^[9]
