Virial masses of RELHICs are robustly recovered from their HI gas profiles via Bayesian nested sampling, with environmental density as a free parameter eliminating systematic mass biases from mass-concentration degeneracies.

Simulations show that 10-30% pollution from supermassive star ejecta reproduces the nitrogen-enhanced abundance pattern of GN-z11 and some other high-z galaxies.
STEPSIC is an open-source code that produces first- and second-order LPT initial conditions for stereographic, cylindrical, and arbitrary-aspect-ratio cuboid domains, achieving sub-percent power spectrum accuracy against linear theory and other generators.
Simulations match observed outflow masses within 0.5 dex but underpredict velocities by an order of magnitude and show face-on galaxies 15-40% more likely to exhibit detectable outflows than edge-on systems.
