An Emulator for the Lyman-alpha Forest
Simeon Bird, Keir K. Rogers, Hiranya V. Peiris +3
We present methods for interpolating between the 1-D flux power spectrum of the Lyman- forest, as output by cosmological hydrodynamic simulations. Interpolation is necessary for…
Bayesian emulator optimisation for cosmology: application to the Lyman-alpha forest
Keir K. Rogers, Hiranya V. Peiris, Andrew Pontzen +3
The Lyman-alpha forest provides strong constraints on both cosmological parameters and intergalactic medium astrophysics, which are forecast to improve further with the next genera…
Cosmological Hydrodynamic Simulations with Suppressed Variance in the Lyman- Forest Power Spectrum
Lauren Anderson, Andrew Pontzen, Andreu Font-Ribera +3
We test a method to reduce unwanted sample variance when predicting Lyman- (ly) forest power spectra from cosmological hydrodynamical simulations. Sample variance arises due…
