Detecting HeliumII reionization from a sudden injection of entropy in the intergalactic medium
Tom Theuns, Saleem Zaroubi, Tae-Sun Kim
The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-ba…

Constraining reionization using the thermal history of the baryons
Joop Schaye, Tom Theuns, Michael Rauch +2
The thermal evolution of the intergalactic medium (IGM) depends on the reionization history of the universe. Numerical simulations indicate that the low density IGM, which is respo…

Measuring the temperature of the intergalactic medium
Joop Schaye, Tom Theuns, Anthony Leonard +1
Numerical simulations indicate that the smooth, photoionized intergalactic medium (IGM) responsible for the low column density Lyman-alpha forest follows a well defined temperature…
