DESCRIPTION:Speakers: Carlos García García (Oxford University Physics)\n
 \nIn this talk I will present an ongoing work towards building a very larg
 e public repository containing data from virtually all relevant projected 
 large-scale-structure datasets\, consistently re-analysed under a common d
 ata analysis framework. The repository consists of a large number of angul
 ar power spectra and their uncertainties\, combining a wide variety of tra
 cers of interesting quantities for cosmology and astrophysics. I will show
 case novel results in cosmology that have been enabled by this framework\,
  such as constraints on the clumpiness parameter S8 that are competitive w
 ith Stage-4 surveys\, the reconstruction of the cosmic growth history or c
 onstraints on baryonic effects with all current weak lensing surveys. Fina
 lly\, I will argue that multi-tracer analyses are the way forward for LSST
  and Euclid if we want to robustly constrain the cosmological parameters a
 nd identify dark energy. Zoom: http://cfp.ciemat.es/zoomae/eventos\n\nht
