Bayesian emulator optimisation for cosmology: application to the Lyman-alpha forest
Bayesian emulator optimisation for cosmology: application to the Lyman-alpha forest
The Lyman-alpha forest provides strong constraints on both cosmological parameters and intergalactic medium astrophysics, which are forecast to improve further with the next generation of surveys including eBOSS and DESI. As is generic in cosmological inference, extracting this information requires a likelihood to be computed throughout a high-dimensional parameter space. …
