Description
In anticipation of the ongoing and upcoming next-generation surveys, we present galaxy catalog by the well-established LGalaxies semi-analytic model and galaxy emission line catalog by post-processing. We have made modifications to the models to solve the time convergence problem and re-calibrated the parameters to accurately reproduce the observed black hole mass function at z~0. Our catalog successfully reproduces various observational properties, such as the galaxy stellar mass function, red galaxy fraction, black hole mass function, and luminosity function of various emission lines at both local and high redshift. Based on our catalog, we have identified that different emission lines have different biases for tracing the matter distribution of the universe. We have developed a fitting formula that describes the bias as a function of luminosity and redshift for different emission line tracers. In addition, our models are applied to the largest cosmological N-body simulation, the Hyper-Millennium project, yielding self-consistent predictions of galaxy properties.
