Late Reionization and the Thermal History of the Intergalactic Medium

During reionization, the intergalactic medium was heated to temperatures between 20-30,000 K. I will discuss the parameter space of this heating and the hydrodynamical response of the IGM to it. I will also discuss implications for z > 5 Lyman-α forest observations, which potentially include sight lines through patches of the Universe that were still undergoing reionization at z = 5.5-6.
