Detection of large scale Ly$\alpha$ absorbers at large angles to the radio axis of high-redshift radio galaxies using SOAR

M. Silva, A. Humphrey, P. Lagos +4

We present an investigation of the properties of the extended Ly$\alpha$ halo and the large-scale \ion{H}{I} absorbing structures associated with 5 high-redshift radio galaxies at z $>$…
