An Anti-halo Void Catalogue of the Local Super-Volume

Abstract

We construct an anti-halo void catalogue of $150$ voids with radii $R>10h^{-1}\mathrm{Mpc}$ in the Local Super-Volume ($<135h^{-1}\mathrm{Mpc}$ from the Milky Way), using posterior resimulation of initial conditions inferred by field-level inference with Bayesian Origin Reconstruction from Galaxies (\codefont{BORG}). We describe and make use of a new algorithm for creating a single, unified void catalogue by combining different samples from the posterior. The catalogue is complete out to $135h^{-1}\mathrm{Mpc}$, with void abundances matching theoretical predictions. Finally, we compute stacked density profiles of those voids which are reliably identified across posterior samples, and show that these are compatible with $\Lambda$CDM expectations once environmental selection (e.g., the estimated $\sim 4\%$ under-density of the Local Super-Volume) is accounted for.
