The probability distribution of cluster formation times and implied Einstein Radii

S. Sadeh, Y. Rephaeli

We provide a quantitative assessment of the probability distribution function of the concentration parameter of galaxy clusters. We do so by using the probability distribution func…

S-Z Power Spectra

Yoel Rephaeli, Sharon Sadeh

There is some observational evidence for earlier evolution of clusters of galaxies than predicted in the standard LambdaCDM model with a Gaussian primordial density fluctuation fie…

Cluster abundances and S-Z power spectra: effects of non-Gaussianity and early dark energy

S. Sadeh, Y. Rephaeli, J. Silk

In the standard Lambda CDM cosmological model with a Gaussian primordial density fluctuation field, the relatively low value of the mass variance parameter (sigma_8=0.74{+0.05}{-0.…

Impact of a non-Gaussian density field on Sunyaev-Zeldovich observables

S. Sadeh, Y. Rephaeli, J. Silk

The main statistical properties of the Sunyaev-Zeldovich (S-Z) effect - the power spectrum, cluster number counts, and angular correlation function - are calculated and compared wi…

The Sunyaev-Zeldovich Effect

Y. Rephaeli, S. Sadeh, M. Shimon

This brief, general review the Sunyaev-Zeldovich (S-Z) effect includes a description of the calculation of the total intensity change and polarization components, a discussion of t…

Sunyaev-Zeldovich Cluster Counts as a Probe of Intra-Supercluster Gas

S. Sadeh, Y. Rephaeli

X-ray background surveys indicate the likely presence of diffuse warm gas in the Local Super Cluster (LSC), in accord with expectations from hydrodynamical simulations. We assess s…
