A direct measure of free electron gas via the kinematic Sunyaev–Zel'dovich effect in Fourier-space analysis
A direct measure of free electron gas via the kinematic Sunyaev–Zel'dovich effect in Fourier-space analysis
We present the measurement of the kinematic Sunyaev-Zel'dovich (kSZ) effect in Fourier space, rather than in real space. We measure the density-weighted pairwise kSZ power spectrum, the first use of this promising approach, by cross-correlating a cleaned Cosmic Microwave Background (CMB) temperature map, which jointly uses both Planck Release 2 …
