Large-scale surveys of the quasar proximity effect

open access: yesThe Open Journal of Astrophysics
The UV radiation from high redshift quasars causes a local deficit in the neutral hydrogen absorption (Lyman-alpha forest) in their spectra, known as the proximity effect.

Quasar Radiative Feedback May Suppress Galaxy Growth on Intergalactic Scales at z = 6.3

open access: yesThe Astrophysical Journal Letters
We present observational evidence that intense ionizing radiation from a luminous quasar suppresses nebular emission in nearby galaxies on intergalactic scales at z = 6.3.
