›Colloquium: Cosmology on small scales
The standard cosmological model LCDM had a remarkable success with
predicting and explaining many properties of the Universe. However, it
faces difficult challenges on small scales with properties and abundances
of dwarf galaxies being the most difficult problems. The situation is
confusing and fluent because it involves complicated physics and
dynamics of smallest galaxies known, which are difficult to observe.
I will give a review of the situation and will discuss possible solution
for some of the problems.
