How massive neutrinos reshape the cosmic web
Leonor N. L. Simões, Krishna Naidoo, Benjamin Joachimi +2
We explore the effects of massive neutrinos on the cosmic web using the FLAMINGO simulations. We classify the cosmic web into voids, sheets, filaments, and clusters, and find that…

Learning the Cosmic Web: Graph-based Classification of Simulated Galaxies by their Dark Matter Environments
Dakshesh Kololgi, Krishna Naidoo, Amelie Saintonge +1
We present a novel graph-based machine learning classifier for identifying the dark matter cosmic web environments of galaxies. Large galaxy surveys offer comprehensive statistical…

Methods for robustly measuring the minimum spanning tree and other field level statistics from galaxy surveys
Krishna Naidoo, Ofer Lahav
Field level statistics, such as the minimum spanning tree (MST), have been shown to be a promising tool for parameter inference in cosmology. However, applications to real galaxy s…
