SIBELIUS-DARK: a galaxy catalogue of the Local Volume from a constrained realisation simulation

Understand

We present SIBELIUS-DARK, a constrained realisation simulation of the local volume to a distance of 200~Mpc from the Milky Way.

• SIBELIUS-DARK is the first study of the \textit{Simulations Beyond The Local Universe} (SIBELIUS) project, which has the goal of embedding a model Local Group-like system within the correct cosmic environment.
• The simulation is dark-matter-only, with the galaxy population calculated using the semi-analytic model of galaxy formation, GALFORM.
• We demonstrate that the large-scale structure that emerges from the SIBELIUS constrained initial conditions matches well the observational data.
