Zel'dovich smearing approximation of the BAO feature for model-agnostic cosmological inference
Aseem Paranjape, Ravi K. Sheth
A model-agnostic description of the baryon acoustic oscillation (BAO) feature in redshift space requires a number of ingredients. Physically, one must describe the impact of cosmol…
Correlation between H emitters and their cosmic web environment at
Ivan Rapoport, Vincent Desjacques, Ehud Behar +1
Future near-infrared spectroscopic galaxy surveys will target high-redshift emission-line galaxies (ELGs) to test cosmological models. Deriving optimal constraints from emission-li…
Scale-dependent bias and mode coupling in redshift-space clustering near the BAO scale
Aseem Paranjape, Ravi K. Sheth
The baryon acoustic oscillation (BAO) feature in the 2-point clustering of biased tracers in redshift space can be described in a model-agnostic manner, relying only on the assumpt…
Model-agnostic basis functions for the 2-point correlation function of dark matter in linear theory
Aseem Paranjape, Ravi K. Sheth
We consider approximating the linearly evolved 2-point correlation function (2pcf) of dark matter in a cosmological model with parameters $\boldsymb…
Eigen-decomposition of Covariance matrices: An application to the BAO Linear Point
Jaemyoung Jason Lee, Farnik Nikakhtar, Aseem Paranjape +1
The Baryon Acoustic Oscillation (BAO) feature in the two-point correlation function (TPCF) of discrete tracers such as galaxies is an accurate standard ruler. The covariance matrix…
