Journal Article
Becker, G. D., D’Aloisio, A., Christenson, H. M., Zhu, Y., Worseck, G., & Bolton, J. S. (2021). The mean free path of ionizing photons at 5 < z < 6: evidence for rapid evolution near reionization. Monthly Notices of the Royal Astronomical Society, 508(2), 1853-1869. https://doi.org/10.1093/mnras/stab2696

The mean free path of ionizing photons, λmfp, is a key factor in the photoionization of the intergalactic medium (IGM). At z ≳ 5, however, λmfp may be short enough that measurements towards QSOs are biased by the QSO proximity effect. We present new...
