[5] ESO 148-2 is also a bright galaxy with a star formation rate of 149 Mʘ yr−1 and an infrared luminosity of LFIR =1011.71 Lʘ.

[6] This infrared luminosity is interpreted as radiation emitting from dust emissions via intense heating of its star formation regions.

[7][8] In the regions of the galaxy, there are type N Wolf-Rayet stars emitting N III λ4641 and He II λ4686 emission, making them the brightest subtype.

The northern nucleus contains a velocity dispersion value agreeing with star formation and emission line ratios in alignment of both LINERS and H II regions.

[12] According to Johnson UBVJHKL and spectroscopy photometry, as well as CCD-imaging, the central region of ESO 148-2 exhibits firm emission lines with a full width at half maximum of 600 kilometers per seconds (km/s).
