GABE: Galaxy Assembly with Binary Evolution
  We developed a new semi-analytic galaxy formation model: Galaxy Assembly with
Binary Evolution (GABE). For the first time we introduce binary evolution into
semi-analytic models of galaxy formation by using Yunnan-II stellar population
synthesis model, which includes various binary interactions. When implementing
our galaxy formation model onto the merger trees extracted from the Millennium
simulation, it can reproduce a large body of observational results. We find
that in the local universe the model including binary evolution reduces the
luminosity at optical and infrared wavelengths slightly, while increases the
luminosity at ultraviolet wavelength significantly, especially in $F_{\rm UV}$
band. The resulting luminosity function does not change very much over SDSS
optical bands and infrared band, but the predicted colors are bluer, especially
when $F_{\rm UV}$ band is under consideration. The new model allows us to
explore the physics of various high energy events related to the remnants of
binary stars, e.g. type Ia supernovae, short gamma-ray bursts and gravitational
wave events, and their relation with host galaxies in a cosmological context.
