BTFR of galaxies. The gray dots are late-type galaxies taken from the SPARC database (Lelli et al. 2016b, 2019), the yellow triangles are early-type galaxies (ETGs) from den Heijer et al. (2015), and the red dot indicates our measurement of the Cen A group. The black line is the best fit of the BTFR, and the dashed line is the ΛCDM prediction assuming the cosmic baryon fraction (Planck Collaboration VI 2020).
