Planck intermediate results: XXXVII. Evidence of unbound gas from the kinetic Sunyaev-Zeldovich effect
By looking at the kinetic Sunyaev-Zeldovich effect (kSZ) in Planck nominal mission data, we present a significant detection of b aryons participating in large-scale bulk flows around central galaxies (CG s) at redshift z≈ 0.1. We estimate the pairwise momentum of the kSZ temperature fluctuations at the positions of the …
