Kosmulator: A Python framework for cosmological inference with MCMC
Renier T. Hough, Robert Rugg, Shambel Sahlu +1
We present Kosmulator, a modular and vectorised Python framework designed to accelerate the statistical testing of cosmological models. As the theoretical landscape expands beyond…

Constraining viscous fluid models in gravity with data
Shambel Sahlu, Renier T. Hough, Amare Abebe +1
We investigate the impact of bulk viscosity on the accelerating expansion and large-scale structure formation of a Universe in which the underlying gravitational interaction is des…

Viability tests of \textit{f(R)}-gravity models with Supernovae Type 1A data
Renier Hough, Amare Abebe, Stefan Ferreira
In this work, we will be testing four different general \textit{f(R)}-gravity models, two of which are the more realistic models (namely the Starobinsky and the Hu-Sawicki models),…
