Top: cumulative distribution of the T_⋆ parameter for field galaxies (green), void galaxies (blue), and FVS galaxies (red). Panel a shows the distributions for the complete galaxy sample, meanwhile panels b and c are for the galaxies residing in groups with 10¹² h⁻¹ M_⊙ < M_group < 10¹³ h⁻¹ M_⊙ and 10¹³ h⁻¹ M_⊙ < M_group < 10¹⁵ h⁻¹ M_⊙, respectively. Inset panels show the ratio between the cumulative fraction of T_⋆ for galaxies inside voids and FVSs, in addition to field galaxies.
