Testing local position invariance with odd multipoles of galaxy clustering statistics
Takuya Inoue, Teppei Okumura, Shohei Saga +1
We investigate cosmological constraints on local position invariance (LPI), a key aspect of the Einstein equivalence principle (EEP), through asymmetric galaxy clustering. The LPI…

Information content in anisotropic cosmological fields: Impact of different multipole expansion scheme for galaxy density and ellipticity correlations
Takuya Inoue, Teppei Okumura, Shohei Saga +1
Multipole expansions have been often used for extracting cosmological information from anisotropic quantities in observation. However, which basis of the expansion is best suited t…
