Simulating Our Cosmological Neighborhood: Mock Catalogs for Velocity Analysis
We describe the construction of an N-body simulation that mimics the true velocity and mass-density fields in a box of side 256\hmpc about the Local Group , and the production of mock catalogs that mimic in detail current catalogs of redshifts and peculiar velocities. Our main purpose is to provide a tool for developing and testing reconstruction methods, but the different components of the method can be used on their own in other applications. The initial conditions are based on the IRAS 1.2Jydoi:10.1086/176826 fatcat:wgup25d2dbh6tdzz3xlymsable
