Context. We present new numerical tools to analyse cosmic void catalogues, implemented inside the CosmoBolognaLib, a large set of open source C++/Python numerical libraries. Aims. The CosmoBolognaLib provides a common numerical environment for cosmological calculations. This work extends these libraries by adding new algorithms for cosmological analyses of cosmic voids, covering the existing gap between theory and observations. Methods. We implemented new methods to model the size function of cosmic voids, in both observed and simulated samples of dark matter and biased tracers. Moreover, we provide new numerical tools to construct unambiguous void catalogues. The latter are designed to be independent of the void finder, in order to allow a high versatility in comparing independent results. Results.

Abstract

Context. We present new numerical tools to analyse cosmic void catalogues, implemented inside the CosmoBolognaLib, a large set of open source C++/Python numerical libraries. Aims. The CosmoBolognaLib provides a common numerical environment for cosmological calculations. This work extends these libraries by adding new algorithms for cosmological analyses of cosmic voids, covering the existing gap between theory and observations. Methods. We implemented new methods to model the size function of cosmic voids, in both observed and simulated samples of dark matter and biased tracers. Moreover, we provide new numerical tools to construct unambiguous void catalogues. The latter are designed to be independent of the void finder, in order to allow a high versatility in comparing independent results. Results. The implemented open source software is available at the GitHub repository of the CosmoBolognaLib. We also provide a full doxygen documentation and some example codes that explain how to use these libraries.
