Without cooling, accreted baryons will not efficiently dissipate their energy and collapse to the centres of haloes to form stars. It is well established that local variations in the amplitude and shape of the spectral energy distribution of the radiation field can drastically alter the cooling rate. Here we introduce deepCool, deepHeat, and deepMetal: methods for accurately modelling the total cooling rates, total heating rates, and metal-line only cooling rates of irradiated gas using artifi","authors_text":"Adrianne Slyz, Harley Katz, Jeremy Blaizot, Joakim Rosdahl, Julien Devriendt, Taysun Kimm, Thomas P.
