Insights into the origin of halo mass profiles from machine learning

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Luisa Lucie-Smith, Susmita Adhikari, Risa H. Wechsler, , | Summary: The mass distribution of dark matter haloes is the result of the hierarchical growth of initial density perturbations through mass accretion and mergers. We use an interpretable machine-learning framework to provide physical insights into the origin […]
