MRC 0051–097 also known as OGC 666 and NYU-VAGC 0306384, is a radio galaxy located in the constellation of Cetus. The redshift of the galaxy is (z) 0.269[1] and it was first discovered by astronomers with the Molongo Radio Telescope in February 1981.[2]

Description

MRC 0051–097 is an elliptical galaxy residing as the brightest cluster galaxy of the WHL J005354.2–092823 galaxy cluster with 47 confirmed galaxy member candidates. The R-band magnitude of the galaxy is 17.03.[3][4] The stellar velocity dispersion is 308 kilometers per seconds while the galaxy effective radius is 15.7 kiloparsecs. The absolute magnitude has been estimated as -23.62 whereas the physical size is 347 kiloparsecs.[5]

The radio source of the galaxy is found mainly compact on sub-arcsecond scales with its total flux density estimated to be 0.337 mJy at 1400 MHz frequencies by NRAO VLA Sky Survey (NVSS) with a calculated solar elongation of 34.9°. The spectral index of the source is -0.83α while the scintillation index is less than 0.02.[6]

A study has found the source is a double with a 162 MHz flux density of 1.634 mJy with a normalized scintillation index of 18.9. Radio imaging by Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) detected four separate components associated with the source.[7] Evidence found the galaxy is found powered by its active galactic nucleus (AGN) with its total log radio luminosity estimated to be 25.86 W Hz−1 and has a 1.4 GHz flux density of 337.4 mJy. The stellar mass of the galaxy is 11.39 M☉.[8] The K-band magnitude of the galaxy is 12.681 based on its isothopal K magnitude calculated by the 2MASS survey.[9]
