Evidence of galaxy cluster rotation in the cosmic microwave background
Samuel Goldstein, J. Colin Hill
We report the first robust evidence for the rotational kinematic Sunyaev-Zel'dovich (rkSZ) effect, produced by the Thomson scattering of cosmic microwave background (CMB) photons o…

A new constraint on the -distortion with FIRAS: implications for feedback models in galaxy formation and cosmic shear measurements
Giulio Fabbian, Federico Bianchini, Alina Sabyr +4
The -type distortion of the blackbody spectrum of the cosmic microwave background radiation probes the pressure of the gas trapped in galaxy groups and clusters. We reanalyze ar…
