Are Clusters Standard Candles? Galaxy Cluster Scaling Relations with the Sunyaev-zeldovich Effect
An extensive sample of galaxy clusters will be available in the coming years, detected through their Sunyaev–Zeldovich effect (SZE). We use a semi–analytic model to study the scientific yield of combining SZE data with X-ray and optical follow-up observations. If clusters at a given redshift zo can be identified with virialized, spherical halos, they populate a well–defined ”fundamental plane” ...
متن کاملPlanck 2015 results - XXIV. Cosmology from Sunyaev-Zeldovich cluster counts
We present cluster counts and corresponding cosmological constraints from the Planck full mission data set. Our catalogue consists of 439 clusters detected via their Sunyaev-Zeldovich (SZ) signal down to a signal-to-noise of six, and is more than a factor of two larger than the 2013 Planck cluster cosmology sample. The counts are consistent with those from 2013 and yield compatible constraints ...
متن کاملOn the Number Density of Sunyaev-Zeldovich Clusters of Galaxies.
If the mean properties of clusters of galaxies are well described by the entropy-driven model, the distortion induced by the cluster population on the blackbody spectrum of the cosmic microwave background radiation is proportional to the total amount of intracluster gas, while temperature anisotropies are dominated by the contribution of 1014 M middle dot in circle clusters. This result depends...
متن کاملKinetic Sunyaev-Zeldovich effect from galaxy cluster rotation
We show how the temperature and the polarisation of the cosmic microwave background are affected by bulk rotation of clusters of galaxies owing to the kinetic Sunyaev-Zeldovich effect. The main effects of rotation are (i) a shift of the position of the peak of the temperature fluctuation relative to the center of the cluster by a few percent of the core radius and (ii) a tilt of the direction o...
متن کاملThe Impact of Galaxy Formation on the Sunyaev-zeldovich Effect of Galaxy Clusters
We study the effects of radiative cooling and galaxy formation on the Sunyaev-Zel’dovich (SZ) observable-mass relations using high-resolution cosmological simulations. The simulations of eleven individual clusters spanning a decade in mass are performed with the shock-capturing eulerian adaptive mesh refinement N-body+gasdynamics ART code. To assess the impact of galaxy formation, we compare tw...
