DESCRIPTION:The possibility that we live in a special place in the univers
 e\, close to the center of a large void\, is an appealing alternative to t
 he prevailing interpretation of the acceleration of the universe in terms 
 of a Lambda-CDM model with a dominant dark energy component. I will introd
 uce models with a large void embedded in a flat Einstein de Sitter space-t
 ime\, and confront them with a plethora of observations\, from Type Ia Sup
 ernovae to Cosmic Microwave Background\, Baryon Acoustic Oscillations data
 \, and kinetic Sunyaev-Zeldovich observations. I will show that void model
 s successfully can explain the observational data\, albeit with some strai
 n\, and comment on new observations\, that may hint the existence of large
  scales flows in the universe\, that could belinked to inhomogeneities on 
 large scales.\n\nhttps://indico.ific.uv.es/event/1648/
