"Dark Matter in Dwarf Spheroidal Galaxies"

Dwarf spheroidal galaxies were thought to be the simplest galaxies in the Universe. They do not have gas or star formation. They are dominated by dark matter. They do not rotate. Recent observational and theoretical results show that the galaxies are not simple. They became a center of one of the most difficult problems in cosmology: too-big-to-fail problem, which is states that structure of large dShp galaxies is not compatible with predictions of the standard cosmological model. I will show results, which show how the problem can be resolved. I will also discuss scenario of the origin of these galaxies.
