  1. 24. Scale-dependent galaxy bias in local-type primordial non-Gaussianities with heavy-tailed models

    Scale-dependent bias is a crucial indicator in the late-time universe for understanding local-type primordial non-Gaussianities. Previous studies have focused on low-order non-Gaussian models characterized by the f_NL (second order), g_NL and tau_NL (third order) parameters, with forecasts made for upcoming large-scale galaxy surveys. In this talk, we extend this framework to models exhibiting...

  2. 25. Divide and Conquer the Cosmos: Patching Simulation beyond Separate Universe

    The separate universe simulation account for the mean density mode, and the mean tidal modes too in its anisotropic extension. I will present some recent work on perfect parallel simulation accounting for all long-wavelength modes through boundary conditions.
