Abstract

fetched live from OpenAlex

Detailed photoionization and radiative acceleration of self-similar magnetocentrifugal accretion disk winds are explored. First, a general-purpose hybrid magnetocentrifugal and radiatively-driven wind model is defined. Solutions are then examined to determine how radiative acceleration modifies magnetocentrifugal winds and how those winds can influence radiative driving in Active Galactic Nuclei (AGNs). For the models studied here, both radiative acceleration by bound-free (``continuum-driving'') and bound-bound (``line-driving'') processes are found to be important, although magnetic driving dominates the mass outflow rate for the Eddington ratios studied (L/L_Edd = 0.001 - 0.1). The solutions show that shielding by a magnetocentrifugal wind can increase the efficiency of a radiatively-driven wind, and also that, within a magnetocentrifugal wind, radiative acceleration is sensitive to both the column in the shield, the column of the wind and the initial density at the base of the wind.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
