Missing thermal energy of the intracluster medium
Missing thermal energy of the intracluster medium
The Sunyaev–Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9σ detection of the SZ signal in the CMB maps of …
