Testing Bump in the Cosmological Power Spectrum Using Dwarf Galaxies
Maxim Zabelkin, Sergey Drozdov, Oleg Skorikov +1
We analyze the possibility of using observational data on nearby dwarf galaxies -- their luminosity functions and spatial distributions -- to constrain deviations of the cosmologic…

Observations of Galaxies at Allow to Test Cosmological Models with Features in the Initial Power Spectrum
S. V. Pilipenko, S. A. Drozdov, M. V. Tkachev +1
The initial power spectrum of density perturbations, generated during the inflationary epoch, is now constrained by observations on scales ~Mpc and has a power-law form. The p…
