unimpeded: A Public Grid of Nested Sampling Chains for Cosmological Model Comparison and Tension Analysis
Dily Duan Yi Ong, Will Handley
Bayesian inference is central to modern cosmology, yet comprehensive model comparison and tension quantification remain computationally prohibitive for many researchers. To address…
The Bayesian view of DESI DR2 with unimpeded: Evidence and tension in a combined analysis with CMB and supernovae across cosmological models
Dily Duan Yi Ong, David Yallup, Will Handley
We apply the framework to perform a fully Bayesian reanalysis of the DESI DR2 data, using nested sampling with to compute evidences for $Î…
A Bayesian Perspective on Evidence for Evolving Dark Energy
Dily Duan Yi Ong, David Yallup, Will Handley
The DESI Collaboration reports a significant preference for a dynamic dark energy model (CDM) over the cosmological constant (CDM) when their data are combined with oth…
Signatures of star formation inside galactic outflows
Dily Duan Yi Ong, Francesco D'Eugenio, Roberto Maiolino +13
Observations have suggested that galactic outflows contain substantial amounts of dense and clumpy molecular gas, creating favourable conditions for igniting star formation. Indeed…
: A Public Nested Sampling Database for Bayesian Cosmology
Dily Duan Yi Ong, Will Handley
Bayesian inference is central to modern cosmology. While parameter estimation is achievable with unnormalised posteriors traditionally obtained via MCMC methods, comprehensive mode…
