Intrinsic alignments of galaxies around cosmic voids
William d'Assignies D., Nora Elisa Chisari, Nico Hamaus +1
The intrinsic alignments of galaxies, i.e., the correlation between galaxy shapes and their environment, are a major source of contamination for weak gravitational lensing surveys.…
A fast estimator for quantifying the shape dependence of the 3D bispectrum
Abinash Kumar Shaw, Somnath Bharadwaj, Debanjan Sarkar +3
The dependence of the bispectrum on the size and shape of the triangle contains a wealth of cosmological information. Here we consider a triangle parameterization which allows us t…
Improved Master for the LSS: Fast and accurate analysis of the two point power spectra and correlation functions
Sukhdeep Singh
We review the methodology for measurements of two point functions of the cosmological observables, both power spectra and correlation functions. For pseudo- estimators, we…
An Analytic Hybrid Halo + Perturbation Theory Model for Small-scale Correlators: Baryons, Halos, and Galaxies
James M. Sullivan, Uros Seljak, Sukhdeep Singh
We update Halo Zeldovich Perturbation Theory (HZPT), an analytic model for the two-point statistics of dark matter, to describe halo and galaxy clustering, and galaxy-matter cross-…
