Introduction to OMEGA

The One-zone Model for the Evolution of GAlaxies (OMEGA) module allows to calculate the global chemical evolution trends of galaxies. From an input star formation history, it uses SYGMA to create as a function of time multiple simple stellar populations with different masses, ages, and initial compositions. OMEGA offers several prescriptions for modeling the star formation efficiency and the evolution of galactic inflows and outflows. For more information on how to use OMEGA, we refer to the GettingStarted and Documentation tabs. Scientific application cases can be found in the publications listed in the Overview tab.
