Dark matter in galaxies
The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology, extragalactic astrophysics, astroparticle physics, as well as in a number of issues in high-energy astrophysics, galactic astronomy, star formation and evolution and general relativity. Not withstanding the general successes of the ΛCDM model in explaining the structure and evolution of the universe, there is a growing conviction that the structural properties of the dark and luminous components in galaxies hold important clues about the nature of dark matter and about the processes that are responsible for galaxy formation. This talk is part of an international initiative known as "Dark Matter Awareness Week".The overall purpose of this event is to increase the awareness of the phenomenology of the mass discrepancy phenomenon in galaxies amongst the many scientists currently working with a theoretical, observational, experimental and simulation approach on issues involving dark matter or its alternatives. The content of the talk will be at the level of a journal club talk with an important dose of review.
