Estimating Dark Matter Halo Masses in Simulated Galaxy Clusters with Graph Neural Networks

Nikhil Garuda, John F. Wu, Dylan Nelson +1

Galaxies grow and evolve in dark matter halos. Because dark matter is not visible, galaxies' halo masses (${\mathrm{M}}_{\mathrm{halo}}$) must be inferred indirectly. We present a graph neur…
