Cosmic-web quenching with DESI DR1: T-Web environments and mass-dependent red/blue classification

Hafiz Inam Ullah, Muhammad Awais, Tonatiuh Matosb +1

We study DESI DR1 galaxies to quantify colour dependence on cosmic web environment for three tracers spanning complementary regimes: BGS ($0.15\le z<0.55$), LRG ($0.6\le z<0.9$), a…
