Metallicity-dependent spectral evolution

P. Traat

We have studied the spectral evolution of stellar populations in function of their heavy element content and star formation, using Geneva and Padova stellar track sets, both coveri…

Steps toward the power spectrum of matter. III. The primordial spectrum

J. Einasto, M. Einasto, E. Tago +5

Observed power spectrum of matter found in Papers I and II is compared with analytical power spectra. Spatially flat cold and mixed dark matter models with cosmological constant an…

Steps toward the power spectrum of matter. II. The biasing correction with sigma_8 normalization

J. Einasto, M. Einasto, E. Tago +5

A new method to determine the bias parameter of galaxies relative to matter is suggested. The method is based on the assumption that gravity is the dominating force which determine…

Steps toward the power spectrum of matter. I.The mean spectrum of galaxies

J. Einasto, M. Einasto, E. Tago +8

We calculate the mean power spectrum of galaxies using published power spectra of galaxies and clusters of galaxies. On small scales we use the power spectrum derived from the 2-di…

HVCs probing a gaseous Galactic halo

P. M. W. Kalberla, J. Kerp, U. Haud

We study the hypothesis that high-velocity clouds (HVCs) may originate from instabilities within the gaseous phase of the Galactic halo. According to the hydrostatic equilibrium mo…

Regularity of the large-scale structure of the Universe

Jaan Einasto

Recent analysis of the distribution of clusters of galaxies is reviewed. Clusters of galaxies located in rich superclusters form a quasiregular lattice. The mean power spectrum of…
