Abstract

It has been common on the last decades to consider that we entered in a precision cosmology era, where the parameter which describe the universe can reach 1% precision. To reach this level of accuracy, a lot of effort has been put both on the observational and the theoretical side in order to create huge databases whose objects, errors, measuring and analysis techniques are efficient and well understood. Using real data and simulations, we intend to contribute to this goal on three fronts: the characterization of type Ia supernovae residing in galaxy clusters, the evaluation and optimization of supernovae observations performed by the J-PAS project and the study errors on the matter power spectrum when measured over galaxy catalogs with photometric redshifts.
