The lcdm model at small scalesMilky way satellites and cusp-core crisis

Resumen

Cosmology-the study of the formation and ultimate fate of structures and galaxies throughout the Universe- is without a doubt one of the most exciting fields in astrophysics today. Over the last twenty years a picture has emerged in which contemporary structures (e.g. galaxies, galaxy groups and clusters, and the filamentary network in-between) have evolved by gravitational amplification of seed inhomogeneities that are likely of quantum origin and were produced shortly after the Big Bang. This picture ties together (observational) measurements of the cosmic background radiation, estimastes of the primordial abundances of the light elements measurements of the clustering of galaxies and, to a more limited extent, the characteristic properties of individual galaxies.
