Over the last two decades, extragalactic surveys have mapped the positions of millions of galaxies over extraordinary volumes, in an effort to understand the dynamics, composition and underlying rules that govern our Universe. Galaxies and the dark matter halos in which they reside are intrinsically connected. That relationship holds information about important processes in galaxy and structure formation, and is key to unlocking the full statistical power of forthcoming redshift surveys and their cosmological analyses. In this seminar, I will consider how the galaxy-halo connection might depend on its position within the cosmic web – the familiar decomposition of large-scale structure in filaments, knots and voids. I will finish by introducing the forthcoming DESI survey, and the role DESI will play in unravelling the galaxy-halo connection within the cosmic web.
