标题： Radiative Transfer Effects during Photoheating of the Intergalactic Medium

摘要： 再电离后星系际介质（IGM）的热历史在很大程度上由光加热决定。 我们证明，忽略辐射转移效应的光加热率计算，在再电离期间和之后严重低估了能量输入。 忽略辐射转移效应导致再电离后氦II电离后的IGM温度过低一个因子二。 我们简要讨论这对IGM的吸收特性以及浅势阱中重子分布的影响。 显示英文摘要

摘要： The thermal history of the intergalactic medium (IGM) after reionization is to a large extent determined by photoheating. Here we demonstrate that calculations of the photoheating rate which neglect radiative transfer effects substantially underestimate the energy input during and after reionization. The neglect of radiative transfer effects results in temperatures of the IGM which are too low by a factor of two after HeII reionization. We briefly discuss implications for the absorption properties of the IGM and the distribution of baryons in shallow potential wells.
