Computing Nonlinear Power Spectra Across Dynamical Dark Energy Model Space with Neural ODEs
Peter L. Taylor
I show how to compute the nonlinear power spectrum across the entire dynamical dark energy model space. Using synthetic CDM data, I train a neural ordinary differential e…

Unified reconstruction of the Lyman-alpha power spectrum with Hamiltonian Monte Carlo
N. G. Karaçaylı, P. L. Taylor
The complex geometry of the Ly forest data has motivated the use of various two-point statistics as alternatives to the three-dimensional power spectrum (), whi…
