Contribution

It presents a detailed measurement and modeling of galaxy power spectrum multipoles from eBOSS data using non-linear perturbation theory, advancing cosmological analysis methods.

Findings

Measured multipole power spectra for NGC and SGC samples.

Modeled the spectra with non-linear perturbation theory.

Provided insights into galaxy clustering at z~0.7.

Abstract

We live in the golden era of cosmology due to next redshift surveys will map a significant volume of the Universe across a wide range of redshifts. We analyze the clustering of the eBOSS luminous red galaxy sample (eBOSS LRG). We measure the multipole power spectra inferred from the NGC sample (107500 galaxies) and SGC sample (67316 galaxies) between redshifts 0.6 and 1.0, with effective redshift zeff=0.695 and zeff=0.704 for NGC and SGC samples, respectively. We use the non-linear perturbation theory to model the the redshift space multipoles of the galaxy power spectrum.
