## Clustering Distortions from Lyman-alpha Radiative Transfer

Introduction Lyman-$\alpha$ emitters and their intensity map are powerful probes of the large-scale structure. Given typically very high optical depths, scatterings with neutral hydrogen have a non-negligible impact on the observed distribution of Lyman-$\alpha$ photons. To study this in detail, we run a suit of radiative transfer (RT) simulations on the Illustris simulation and investigate two possible distortion effects arising from RT in real space as well as in redshift space for the two-point correlation function.

## Clustering Distortions from Lyman-alpha Radiative Transfer - A short introduction

The dimensionally split power spectrum/two-point correlation are standard tools for constraining the cosmological model from redshift surveys. Given the Lyman-alpha emission line, I will try to motivate what significant distortions from the line's …

## Clustering Distortions from Lyman-alpha Radiative Transfer

Lyman-alpha based emission line surveys are prone to errors in their interpretation due to the complex radiative transfer for this line. We address this issue by running full radiative transfer simulations on the Illustris simulations and generate …

## Radiative Transfer Simulations of Lyman Alpha Emitters on Cosmological Scales

Lyman-alpha emitters can be used as probes of the large-scale structure at intermediate redshifts. Recent work discusses a possible distortion from radiative transfer effects of the resonant Lyman-alpha line on the observed clustering statistics, …
