Downsizing of the blue cloud and the influence of galaxy size on mass quenching over the last eight billion years

Key Points

• Mass quenching significantly impacts the blue cloud's size and composition over eight billion years, with cosmic evolution driving these changes.
• Findings indicate that larger galaxies demonstrate a more pronounced quenching effect than smaller ones, influencing star formation rates definitively.
• Observational analysis focused on mass quenching variations among galaxies of varying sizes reveals vital trends in cosmic evolution.
• Insights into galactic dynamics enhance our understanding of star formation, suggesting that mass quenching is a critical factor in the blue cloud's downsizing.
