Towards a self-consistent analysis of the anisotropic galaxy two- and three-point correlation functions on large scales: application to mock galaxy catalogues
Naonori S. Sugiyama, Shun Saito, Florian Beutler +1
We establish a practical method for the joint analysis of anisotropic galaxy two- and three-point correlation functions (2PCF and 3PCF) on the basis of the decomposition formalism…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: measurement of the BAO and growth rate of structure of the emission line galaxy sample from the anisotropic power spectrum between redshift 0.6 and 1.1
Arnaud de Mattia, Vanina Ruhlmann-Kleider, Anand Raichoor +33
We analyse the large-scale clustering in Fourier space of emission line galaxies (ELG) from the Data Release 16 of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spect…
Impact of Relativistic Effects on the Primordial Non-Gaussianity Signature in the Large-Scale Clustering of Quasars
Mike Shengbo Wang, Florian Beutler, David Bacon
Relativistic effects in clustering observations have been shown to introduce scale-dependent corrections to the galaxy over-density field on large scales, which may hamper the dete…
Modeling relativistic contributions to the halo power spectrum dipole
Florian Beutler, Enea Di Dio
We study the power spectrum dipole of an N-body simulation which includes relativistic effects through ray-tracing and covers the low redshift Universe up to …
The relativistic galaxy number counts in the weak field approximation
Enea Di Dio, Florian Beutler
We present a novel approach to compute systematically the relativistic projection effects at any order in perturbation theory within the weak field approximation. In this derivatio…
Ensemble Slice Sampling: Parallel, black-box and gradient-free inference for correlated & multimodal distributions
Minas Karamanis, Florian Beutler
Slice Sampling has emerged as a powerful Markov Chain Monte Carlo algorithm that adapts to the characteristics of the target distribution with minimal hand-tuning. However, Slice S…
