B2 1116+28

B2 1116+28 has been categorized as a weak emission-line radio galaxy (WLRG). Its host is described as an ordinary isolated elliptical galaxy with a boxy morphology and has an undisturbed appearance.^[4] When observed with the Westerbork Synthesis Radio Telescope, it contains a wide angle tail radio source. The radio core is found resolved with traces of radio emission depicted with low surface brightness and orientated at position angle of 100°.^[3] The total luminosity of the core is estimated around 7.16 × 10³⁹ erg s⁻¹.^[5] There are presence of two outer radio lobes with a measured spectra indexes of 1.4 ± 0.2.^[3]

Further radio observations also detected a presence of a central component with the polarization angle being 88° and a rotation measure of around 7 radii square meter. The radio spectrum of the source is mainly straight between the frequencies ranging from 408 MHz and 10.55 GHz frequencies.^[6] There are presence of two radio jets based on arcsecond imaging resolutions, with evidence of a two-sided structure positioned in the same direction like the jets.^[7] Evidence also found the main jet is located on the western direction.^[8] A study also found detections of polarization, with the eastern lobe being polarized at 15% while the central region is polarized at 8%. Meanwhile, the polarization is the highest in the western lobe, exceeding more than 20%.^[6]

An extended emission line region has been detected in B2 1116+28. Based on observations, the region is described to have a circular appearance and is mainly associated with a radio source depicted having evidence of an extended structure in the position angle of 80°.^[5]
