Description
We have constructed all-sky Compton parameters maps, y-maps, of the
thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored
component separation algorithms to the 30 to 857 GHz frequency channel
maps from the Planck satellite. These reconstructed y-maps are delivered
as part of the Planck 2015 release. The y-maps are characterized in
terms of noise properties and residual foreground contamination, mainly
thermal dust emission at large angular scales, and cosmic infrared
background and extragalactic point sources at small angular scales.
Specific masks are defined to minimize foreground residuals and
systematics. Using these masks, we compute the y-map angular power
spectrum and higher order statistics. From these we conclude that the
y-map is dominated by tSZ signal in the multipole range, 20
<ℓ< 600. We compare the measured tSZ power spectrum and higher
order statistics to various physically motivated models and discuss the
implications of our results in terms of cluster physics and cosmology.
