Abstract

fetched live from OpenAlex

Mirror matter is a dark matter candidate that consists of an exact copy of the Standard Model gauge group. Assuming the Z2 mirror symmetry between ordinaryand mirror matter is unbroken, the chemical and nuclear processes of each sector havethe same rates, which makes the model fully predictive given the temperature anddensity of mirror matter. In this thesis, we study the cosmology of mirror matter,focusing on structure formation, in order to constrain the parameters of this theory.We first give a review of the evidence for dark matter and the tensions within the colddark matter paradigm. We then go over the main events of standard cosmology in boththe visible and mirror sectors in order to highlight their differences. Next, we present asemi-analytical model of galaxy formation that allows us to simulate the formation ofmirror structures. After presenting the results of our analysis, we constrain the modelusing astronomical observations

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
