Measuring the thermal and ionization state of the low-$z$ IGM using likelihood free inference

Teng Hu, Vikram Khaire, Joseph F. Hennawi +6

We present a new approach to measure the power-law temperature density relationship $T=T_0(\rho /\bar{\rho }{)}^{\gamma -1}$ and the UV background photoionization rate ${\Gamma }_{\mathrm{HI}}$ of the IGM base…
