Notes. Basic radio properties of group galaxies in COSMOS. Columns 1 & 2: The 3 GHz radio ID (Smolčić et al. 2017a) and the X-ray galaxy group ID (Gozaliasl et al. 2019, and in prep.), respectively. Columns 3 & 4: Right Ascension (R.A.) and Declination (Dec) of the radio position in degrees, respectively. Columns 5 & 6: Right Ascension (R.A.) and Declination (Dec) of the X-ray galaxy group position in degrees, respectively. Columns 7 & 8: Redshift of the radio source and the X-ray galaxy group, respectively. The character ’s’ denotes spectroscopic and ’p’ denotes photometric redshift for the X-ray groups. Column 9: Radio luminosity at 1.4 GHz in W Hz⁻¹. Column 10: X-ray galaxy group luminosity and error in 10⁴² erg s⁻¹. Column 11: Halo mass at M_200c in 10¹³ M_⊙ and error. Column 12: Virial radius of the group R_200c in degrees. Column 13: BBG rank, where 0 denotes if the group galaxy is the brightest of the X-ray galaxy group and values > 0 are for satellite galaxies. Column 14: Radio classification based on a combination of the radio excess parameter (Smolčić et al. 2017b; Delvecchio et al. 2017) and objects having radio jets (Vardoulaki et al. 2021); ’AGN’ exhibit radio excess or have radio jets, while ’SFG’ do not.
