| Zusammenfassung: | We use <i>Planck<i/> data to detect the cross-correlation between the thermal Sunyaev-Zeldovich (tSZ) effect and the infrared emission from the galaxies that make up the the cosmic infrared background (CIB). We first perform a stacking analysis towards <i>Planck<i/>-confirmed galaxy clusters. We detect infrared emission produced by dusty galaxies inside these clusters and demonstrate that the infrared emission is about 50% more extended than the tSZ effect. Modelling the emission with a Navarro-Frenk-White profile, we find that the radial profile concentration parameter is c<sub>500<sub/> = 1.00<sup>+0.18<sup/><sub>-0.15<sub/> . This indicates that infrared galaxies in the outskirts of clusters have higher infrared flux than cluster-core galaxies. We also study the cross-correlation between tSZ and CIB anisotropies, following three alternative approaches based on power spectrum analyses: (i) using a catalogue of confirmed clusters detected in <i>Planck<i/> data; (ii) using an all-sky tSZ map built from <i>Planck<i/> frequency maps; and (iii) using cross-spectra between <i>Planck<i/> frequency maps. With the three different methods, we detect the tSZ-CIB cross-power spectrum at significance levels of (i) 6<i>σ<i/>; (ii) 3<i>σ<i/>; and (iii) 4<i>σ<i/>. We model the tSZ-CIB cross-correlation signature and compare predictions with the measurements. The amplitude of the cross-correlation relative to the fiducial model is <i>A<i/><sub>tSZ−CIB<sub/> = 1.2 ± 0.3. This result is consistent with predictions for the tSZ-CIB cross-correlation assuming the best-fit cosmological model from <i>Planck<i/> 2015 results along with the tSZ and CIB scaling relations. |
