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

Abstract

Scaling relations trace the formation and evolution of galaxy clusters. We exploited multi-wavelength surveys -- the XXL survey at \emph{XMM-Newton} 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 AGN feedback in groups. From the multi-variate analysis, we found some evidence for steeper than self-similar slopes for gas mass (${\beta }_{m_{\text{g}}|m}=1.73\pm 0.80$) and luminosity (${\beta }_{l|m}=1.91\pm 0.94$) and a nearly self-similar slope for the temperature (${\beta }_{t|m}=0.78\pm 0.43$). Intrinsic scatters of X-ray properties appear to be positively correlated at a fixed mass (median correlation factor ${\rho }_{X_1{X}_2|m}\sim 0.34$) due to dynamical state and merger history of the halos. Positive correlations with the weak lensing mass (median correlation factor ${\rho }_{m_{\text{wl}}X|m}\sim 0.35$) can be connected to triaxiality and orientation. Comparison of weak lensing and hydrostatic masses suggests a small role played by non-thermal pressure support ($9\pm 17\%$).
