On the minimum number of radiation field parameters to specify gas cooling and heating functions
David Robinson, Camille Avestruz, Nickolay Y. Gnedin
Fast and accurate approximations of gas cooling and heating functions are needed for hydrodynamic galaxy simulations. We use machine learning to analyze atomic gas cooling and heat…

Cosmic Reionization on Computers: Statistical Properties of the Distributions of Mean Opacities
Ella Werre, David Robinson, Camille Avestruz +1
Quasar absorption lines provide a unique window to the relationship between galaxies and the intergalactic medium during the Epoch of Reionization. In particular, high redshift qua…

The effects of different cooling and heating function models on a simulated analog of NGC300
David Robinson, Camille Avestruz, Nickolay Y. Gnedin +1
Gas cooling and heating rates are vital components of hydrodynamic simulations. However, they are computationally expensive to evaluate exactly with chemical networks or photoioniz…
