Cosmological Implications of X-ray Clusters of Galaxies

چکیده
Cosmological implications of clusters of galaxies are discussed with particular attention to their importance in probing the cosmological parameters. More specifically we compute the number counts of clusters of galaxies, LogN–LogS relation, in X-ray and submm bands on the basis of the Press–Schechter theory. We pay particular attention to a set of theoretical models which well reproduce the ROSAT 0.5-2 keV band LogN–LogS , and explore possibilities to break the degeneracy among the viable cosmological models.

X-ray Selected Clusters of Galaxies
Three topics will be presented in this paper: 1) study of the clusters and groups of galaxies found serendipitously in the North Ecliptic Pole (NEP) region of the ROSAT all-sky survey; 2) the highest redshift clusters found in the EMSS and the cosmological implications of their very existence; 3) the gravitational lensing in the EMSS X-ray selected clusters of galaxies observed by the Hubble Sp...

متن کاملLarge Scale Structure and X-ray Clusters of Galaxies
I review 1 recent progress in the study of the large-scale structure of the Universe through the distribution of clusters of galaxies, concentrating on new results using X-ray selected samples. After discussing the importance of understanding the properties of the tracers used to map structure and their relation to the underlying mass, I elaborate on the advantages and disadvantages of clusters...
متن کاملA reanalysis of the X - ray luminosities of clusters of galaxies in the EMSS sample with 0 . 3 < z < 0 . 6 . S . C . Ellis
A reanalysis of the X-ray luminosities of clusters of galaxies in the EMSS sample with 0.3<z<0.6. ABSTRACT The X-ray luminosities of the Einstein Extended Medium Sensitivity Survey (EMSS) clusters of galaxies with redshifts 0.3< z <0.6 are remeasured using ROSAT PSPC data. It is found that the new luminosities are on average 1.18±0.08 times higher than previously measured but that this ratio de...
متن کاملDetermining Distances to Clusters of Galaxies Using Resonant X-ray Emission Lines
Bright clusters of galaxies can be seen out to cosmological distances, and thus they can be used to derive cosmological parameters. Although the continuum X-ray emission from the intra-cluster gas is optically thin, the optical depth of resonant lines of ions of heavy elements can be larger than unity. In this Letter we study the feasibility of deriving distances to clusters of galaxies by dete...
