The Habitability Trade-off: Chemical Decoupling And Quenching In Massive Galaxies
Massive galaxies experience complex evolutionary processes, including mergers and gas accretion, which can disrupt the chemical equilibrium between their stellar and gaseous components.

Simulating Turbulence In A Galaxy
From the ocean’s rolling swells to the bumpy ride of a jetliner, turbulence is everywhere. It breaks large waves into smaller ones, cascading energy across scales. It is ubitquitous throughout […]
