4. Sunyaev & Zel'dovich Effect
1) SZ effect depends on the projection of n along the line of sights
2) SZ effect is independent of redshift
1) Combination of SZ and X-ray observations gives important information
on the gas structure ;
Combination of SZ and X-ray observations provide information on the cluster
Distance (estimate of H0)
2) SZ observations allow to observe (in principle) all the clusters in the universe
