Nonlinear Information from DESI Luminous Red Galaxies: An Emulator-Based Analysis of Pre- and Post-Reconstruction Power Spectra

Yuting Wang, Gong-Bo Zhao, Kazuya Koyama +61

We present joint measurements of the pre- and post-reconstruction power spectra, $P_{\mathrm{pre}}$ and $P_{\mathrm{post}}$, together with their cross-power spectrum, $P_{\mathrm{cross}}$, for th…
