Abstract

fetched live from OpenAlex

In this work, we investigate the dynamical influence that external, triaxial and tumbling halos may exercise on disks that may lie embedded in them. Such halo configurations are noted in cosmological simulations, to typically rotate about their short axes, with tumbling periods of the order of a Hubble time. Thus, such halos can exert a slowly changing external torque on disks, affecting disk evolution in the process. Another source of complex dynamical effects is the probable misalignment between a disk and a triaxial dark halo. In this work, we conduct a series of experiments in which we explore the effect of a slowly changing quadrupolar tidal potential on N-body models of our Galaxy and M31; our particular aim is to check if this can induce disk structures such as bars, spirals and warps!

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
