Query: Observaci\'on de lentes gravitatorias con ALMA   Gravitational lensing is a fundamental tool for cosmology. A recent
instrument which will provide more information for models of these objects is
ALMA. Our goal is to select lens candidates to observe with ALMA and then model
them using GravLens Software. We had selected 12 quadruple images systems from
the CASTLES database, which show a high probability of observing extended
sources in the submillimetric range. These new data will allow us to improve
existing models.
