The build-up the colour-magnitude relation in galaxy cluters since z ~ 0.8

Key Points

• The evolution of the colour-magnitude relation shows important shifts since z ~ 0.8.
• Key evidence indicates a notable change in the relationship between colour and magnitude over time.
• Observational analysis of galaxy clusters across different redshifts shows growth in the colour-magnitude relation.
• This highlights the dynamic nature of galaxy clusters and the importance of examining their history.
