XXL Survey groups and clusters in the Hyper Suprime-Cam Survey. Scaling relations between X-ray properties and weak lensing mass

Scaling relations trace the formation and evolution of galaxy clusters, We exploited multi wavelength surveys - the XXL survey at XMM-Newlon in the X-ray band, and the Hyper Suprime-Cam Subaru Strategic Program for optical weak lensing - to study an X-ray selected, complete sample of clusters and groups. The scalings of gas mass, temperature, and soft band X-ray luminosity with the weak lensing mass show imprints of radiative cooling and active galactic nucleus feedback in groups. From the multi-variate analysis, we found some evidence for steeper than self-similar slopes for gas mass (beta(mg vertical bar m) = 1.73 +/- 0.80) and luminosity (beta(l vertical bar m) = 1.91 +/- 0.94) and a nearly self-similar slope for the temperature (beta(t vertical bar m) = 0.78 +/- 0.43). Intrinsic scatters of X-ray properties appear to be positively correlated at a fixed mass (median correlation factor rho(X1X2 vertical bar m) similar to 0.34) due to dynamical state and merger history of the haloes. Positive correlations with the weak lensing mass (median correlation factor rho(mw1X vertical bar m) similar to 0.35) can he connected to triaxiality and orientation. Comparison of weak lensing and hydrostatic masses suggests a small role played by non-thermal pressure support (9 +/- 17 per cent).
