Histogram of galaxy-morphology in different environments. In both panels, we show the percentage fraction of T-Type with regard to the total galaxy population, and we indicate the separation between ETGs and LTGs with a yellow dashed line, that is, at T = 0; Top panel: Purple triangles indicate galaxies in pristine filamentary environments and coral squares indicate those outside filaments; Lower panel: Purple triangles (solid lines) indicate galaxy-pairs in filaments, purple circles (dashed lines) indicate galaxy-groups in filaments, and coral squares indicate galaxy-pairs outside filaments.
