Structure formation in the quintessential Universe
Ewa L. Lokas
I review the main characteristics of structure formation in the quintessential Universe. Assuming equation of state w=p/\varrho=$const I provide a brief description of the backgrou…
Dark matter distribution in dwarf spheroidal galaxies
Ewa L. Lokas
We study the distribution of dark matter in dwarf spheroidal galaxies by modelling the moments of their line-of-sight velocity distributions. We discuss different dark matter densi…
Nonlinear evolution of spherical perturbation in a non-flat Universe with cosmological constant
Ewa L. Lokas, Yehuda Hoffman
We generalize the spherical collapse model for the formation of bound objects to apply in a Universe with arbitrary positive cosmological constant. We calculate the critical condit…
Velocity dispersions of dwarf spheroidal galaxies: dark matter versus MOND
Ewa L. Lokas
We present predictions for the line-of-sight velocity dispersion profiles of dwarf spheroidal galaxies and compare them to observations in the case of the Fornax dwarf. The predict…
