The formation and evolution of galaxies cannot be separated from large scale structure growth. Dark matter halos (and, therefore, galaxies) form and grow within the cosmic web - the classification of large-scale structure as distinct environments, namely voids, walls, filaments and nodes. Thanks to the rapid development of extragalactic spectroscopic redshift surveys and cosmological simulations over the last two decades, we are now able to measure the impact of the cosmic web on galaxies and halos in observations and in simulations. In this chapter we summarise the state of play in our understanding of the link between dark matter halos, galaxies, and the cosmic web.

  1. Enabling Cosmic Web Analysis at Gigaparsec Scales: A Multi Block Approach for DisPerSE

    astro-ph.GA 2026-07 conditional novelty 7.0 of 10

    A circumsphere-filtered, block-wise 'frozen-core' tiling lets DisPerSE map filaments at gigaparsec scales, yielding a 92-million-halo filament catalogue and a mass-connectivity power law A≈0.27-0.32.

  2. Tracing Large-Scale Structure Morphology with Multiwavelength Line Intensity Maps

    astro-ph.CO 2025-08 conditional novelty 6.0 of 10

    CO(1-0) line intensity maps trace the cosmic web's filaments and sheets more strongly than HI 21-cm maps, and SKA2-Mid could recover this structure at z~1.4.

  3. COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?

    astro-ph.GA 2026-06 unverdicted novelty 5.0 of 10

    Quiescent galaxies cluster more strongly than star-forming ones by 0.5-1 dex after halo-mass matching, with one-halo conformity up to z~2 that disappears at higher redshifts.

  4. Cosmology with Multi-Wavelength Line Intensity Mapping Synergies in the SKAO Era

    astro-ph.CO 2026-06 unverdicted novelty 2.0 of 10

    Reviews how cross-correlating SKAO 21-cm LIM with other lines like [CII], CO, and Ly-alpha can mitigate systematics, enhance sensitivity, and disentangle cosmological from astrophysical parameters.

  5. Cosmology with Intensity Mapping via Statistics Beyond the Power Spectrum in the SKAO Era

    astro-ph.CO 2026-06 unverdicted novelty 2.0 of 10

    Reviews multiple higher-order statistics for 21-cm intensity mapping and forecasts their detectability with SKAO, incorporating noise and foreground effects.
