Constraining the temperature–density relation of the intergalactic medium with the Lyman-alpha and beta forests
The post-reionization thermal state of the intergalactic medium is characterized by a power-law relationship between temperature and density, with a slope determined by the parameter γ. We describe a new method to measure γ using the ratio of flux curvature in the Lyman α and β forests. At a given r...
