“We are Missing Something” -Dwarf Galaxies Contradict Cosmological Models

  Cosmological simulations include dozens of prescriptions to describe the 13.8-billion-year evolution of the Universe, including numerical recipes for dark energy (so-called lambda), weakly interacting cold dark matter, gas accretion onto primordial galaxies, star formation and evolution, and feedback from quasars and supernovae. The outcome of these lambda cold dark matter simulations reproduce many of … Continue reading “We are Missing Something” -Dwarf Galaxies Contradict Cosmological Models
