The ACCEL2 Project: Precision Measurements of EFT Parameters and BAO Peak Shifts for the Lyman- Forest
Roger de Belsunce, Shi-Fan Chen, Mikhail M. Ivanov +4
We present precision measurements of the bias parameters of the one-loop power spectrum model of the Lyman-alpha (Lya) forest, derived within the effective field theory of large-sc…
