Paper CCXX: Little Red Dots as Early Brane Focal Zones

Key Points

• The aim is to analyze star formation efficiency in proto-sump focal zones at high redshifts.
• Analyzed star formation efficiency using relationships between black hole mass and proto-sump mass at redshifts z = 4–8.
• Calculated ηSF based on the ratio of black hole mass to proto-sump mass (MBH/Msump).
• Investigated the transition point (zLRD) and corrected the efficiency equations for lower mass ratios.
• Peak star formation efficiency asymptotically approaches 1 as mass ratio R increases to infinity.
• Half-efficiency is achieved at a mass ratio of R = 1, influencing star formation rates in early galaxies.
• The transition redshift for little red dots is approximately 4.5 for black hole masses around 10^8 solar masses.
