A Perturbative Approach to the Redshift Space Correlation Function: Beyond the Standard Model

Understand

We extend our previous redshift space power spectrum code to the redshift space correlation function.

• Here we focus on the Gaussian Streaming Model (GSM).
• Again, the code accommodates a wide range of modified gravity and dark energy models.
• For the non-linear real space correlation function used in the GSM, we use the Fourier transform of the RegPT 1-loop matter power spectrum.
