A comparison of optimisation algorithms for high-dimensional particle and astrophysics applications
Optimisation problems are ubiquitous in particle and astrophysics, and involve locating the optimum of a complicated function of many parameters that may be computationally expensive to evaluate.

CosmoBit: A GAMBIT module for computing cosmological observables and likelihoods
We introduce $\sf{CosmoBit}$, a module within the open-source $\sf{GAMBIT}$ software framework for exploring connections between cosmology and particle physics with joint global fits.

Strengthening the bound on the mass of the lightest neutrino with terrestrial and cosmological experiments
We determine the upper limit on the mass of the lightest neutrino from the most robust recent cosmological and terrestrial data.

$\textsf{Xsec}$: the cross-section evaluation code
The evaluation of higher-order cross-sections is an important component in the search for new physics, both at hadron colliders and elsewhere.

Reinterpretation of LHC Results for New Physics: Status and Recommendations after Run 2
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum.

Global analyses of Higgs portal singlet dark matter models using GAMBIT
In all Higgs portal models, we find parameter regions that can explain all of dark matter and give a good fit to all data.

Comparison of statistical sampling methods with ScannerBit, the GAMBIT scanning module
We subject Diver and three other samplers (the nested sampler MultiNest, the MCMC GreAT, and the native ScannerBit implementation of the ensemble Monte Carlo algorithm T-Walk) to a battery of statistical tests.

Effect of electromagnetic dipole dark matter on energy transport in the solar interior
We show that dark matter with an anapole moment of $\sim1\mathrm{GeV}^{-2}$ or magnetic dipole moment of $\sim10^{-3}\mu_p$ can improve the sound-speed profile, small frequency separations and convective zone radius with respect to the Standard Solar Model.

Constraints on cosmic strings from ultracompact minihalos
We perform a detailed study of the accretion of dark matter onto cosmic string loops and compute the resulting mass distribution of UCMHs.
