COLÓQUIO- IFUSP: Measuring cosmology with imaging surveys: current results and prospects
Currently our universe seems to be dominated by a dark energy component with dark matter. We have no clue what either of these components is. On the other hand the old candidate for the dark matter spot is currently uncounted for in the cosmological model. I shall discuss the constraints imposed by cosmological measurements on the neutrino mass as well as on dark energy models.
