Stellar mass at z = 0 as a function of the estimated stellar mass at z ≃ 5. Data are colour-coded by the fraction of assembled stellar mass by z ≃ 5. The Perseus integrated sample is connected by vertical dashed blue lines to the results of the radial analysis (cyan stars). Open upside-down blue triangles indicate the radial results on Virgo massive ETGs by Martocchia et al. (2025). The dotted red line represents assembled fractions of 100%, while the solid, dashed, and dash-dotted blue lines indicate the stellar masses found for red quiescent galaxies with JWST at z > 4.6 by Carnall et al. (2023, 2024), de Graaff et al. (2025), and Barrufet et al. (2025). Compilation from Antwi-Danso et al. (2025).
