BAO cosmology in non-spatially flat background geometry from BOSS+eBOSS and lessons for future surveys
(IOP Publishing, 2024)We study the impact of the assumption of a non-flat fiducial cosmology on the measurement, analysis and interpretation of BAO distance variables, along and across the line-of-sight. The assumption about cosmology enters ... -
Evidence for baryon acoustic oscillations from galaxy–ellipticity correlations
(Springer, 2023)The Baryon Acoustic Oscillations (BAO) feature in the clustering of galaxies or quasars provides a "standard ruler" for distance measurements in cosmology. In this work, we report a 2∼3σ signal of the BAO dip feature in ...
