Evolution of galaxy clusters in MDM cosmologies
N. A. Arkhipova, T. Kahniashvili, V. N. Lukash
The time evolution of galaxy cluster abundance is used to constrain cosmological parameters in dark matter models containing a fraction of hot particles (massive neutrino). We test…

Current status of cosmological MDM model
E. V. Mikheeva, V. N. Lukash, N. A. Arkhipova +1
An analysis of cosmological models in spatially flat Friedmann Universe with cosmic gravitational wave background and zero -term is presented. The number of free parameters is e…

Observational Constraints for Power-law spectra of Density Perturbations
N. A. Arkhipova, V. N. Lukash, E. V. Mikheeva
We present an analysis of cosmological models with mixed dark matter (spectrum slope of density perturbations , hot dark matter abundance ) i…
