Dark Matter in Groups and Clusters of Galaxies
J. Einasto, M. Einasto
A short story of dark matter as an example of a scientific revolution is given. The characteristics of stellar populations are compared with those of dark halos. The mean mass-to-l…
Large Scale Structure of the Universe: Current Problems
J. Einasto
The mean power spectrum of galaxies is compared with theoretical models. Possibilities to explain the observed power spectrum are discussed. Superclusters and voids form a quasi-re…
The supercluster-void network V. Alternative evidence for its regularity
O. Toomet, H. Andernach, J. Einasto +4
The distribution of Abell clusters of galaxies is analysed to study the regularity of the supercluster-void network. A new geometric method sensitive to the regularity of the locat…
Comparing estimators of the galaxy correlation function
Maria-Jesus Pons-Borderia, Vicent J. Martinez, Dietrich Stoyan +2
We present a systematic comparison of some usual estimators of the 2--point correlation function, some of them currently used in Cosmology, others extensively employed in the field…
Metallicity Dependence of Starburst Spectra
P. Traat
We discuss on the basis of our evolutionary spectral models the impact of chemical composition on the spectrum of stellar population formed in the starburst. Their metallicity rang…
The Power Spectrum of Clusters of Galaxies and the Press-Schechter Approximation
Mirt Gramann, Ivan Suhhonenko
We examine the power spectrum of clusters in the Press-Schechter (PS) theory and in N-body simulations to see how the power spectrum of clusters is related to the power spectrum of…
