Prediction of Individual Halo Concentrations Across Cosmic Time Using Neural Networks

Prediction of Individual Halo Concentrations Across Cosmic Time Using Neural Networks

The concentration of dark matter haloes is closely linked to their mass accretion history. We utilize the halo mass accretion histories from large cosmological <i>N</i>-body simulations as inputs for our neural networks, which we train to predict the concentration of individual haloes at...
