Welcome to PRIYA’s documentation!
PRIYA (/PRih-Yaa/) is a cosmological simulation suite that uses Astrid galaxy formation model to simulate the formation and evolution of galaxies in the Universe until redshift two. The science goal of PRIYA is to forward simulate Lyman alpha forest, the absorption features from the neutral hydrogen in the intergalactic medium, and to study cosmology from the Lyman alpha forest under the influence of galaxy formation. PRIYA consists of 60 low-fidelity simulations and 3 high-fidelity simulations, the subgrid model relies on the Astrid galaxy formation model, including the star formation, AGN feedback, and inhomogeneous HI/HeII reionization models.
