Abstract
We present a simple physical model for populating dark matter halos with Lya emitters (LAEs) and predict the properties of LAEs at z 3-7. The central tenet of this model is that the Lya luminosity is proportional to the star formation rate (SFR) which is directly related to the halo mass accretion rate. The only free parameter in our model is then the star formation efficiency (SFE). An efficiency of 2.5% provides the best fit to the Lya luminosity function (LF) at redshift z = 3.1, and we use this SFE to construct Lya LFs at other redshifts. Our model reproduces the Lya LFs, stellar ages, SFR 1-10 M sun yr1, stellar masses ~107to108 M sun, and the clustering properties of LAEs at z 3-7. We find the spatial correlation lengths ro 3-6 h 1 Mpc, in agreement with the observations. Finally, we estimate the field-to-field variation 30% for current volume and flux limited surveys, again consistent with observations. Our results suggest that the star formation, and hence Lya emission in LAEs can be powered by accretion of new material. Relating the accreted mass, rather than the total mass, to the Lya luminosity of LAEs naturally gives rise to their duty cycle.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
