CosmoBit: A GAMBIT module for computing cosmological observables and likelihoods

Abstract

We introduce $\mathsf{CosmoBit}$, a module within the open-source $\mathsf{GAMBIT}$ software framework for exploring connections between cosmology and particle physics with joint global fits. $\mathsf{CosmoBit}$ provides a flexible framework for studying various scenarios beyond $\Lambda$CDM, such as models of inflation, modifications of the effective number of relativistic degrees of freedom, exotic energy injection from annihilating or decaying dark matter, and variations of the properties of elementary particles such as neutrino masses and the lifetime of the neutron. Many observables and likelihoods in $\mathsf{CosmoBit}$ are computed via interfaces to $\mathsf{AlterBBN}$, $\mathsf{CLASS}$, $\mathsf{DarkAges}$, $\mathsf{MontePython}$, $\mathsf{MultiModeCode}$, and $\mathsf{plc}$. This makes it possible to apply a wide range of constraints from large-scale structure, Type Ia supernovae, Big Bang Nucleosynthesis and the cosmic microwave background. Parameter scans can be performed using the many different statistical sampling algorithms available within the $\mathsf{GAMBIT}$ framework, and results can be combined with calculations from other $\mathsf{GAMBIT}$ modules focused on particle physics and dark matter. We include extensive validation plots and a first application to scenarios with non-standard relativistic degrees of freedom and neutrino temperature, showing that the corresponding constraint on the sum of neutrino masses is much weaker than in the standard scenario.
