Clustering of DESI galaxies split by thermal Sunyaev-Zeldovich effect

M. Rashkovetskyi, D. J. Eisenstein, J. Aguilar +46

The thermal Sunyaev-Zeldovich (tSZ) effect is associated with galaxy clusters - extremely large and dense structures tracing the dark matter with a higher bias than isolated galaxi…
