TÍTULO:
The J-Surveys: the sky in multi-color

RESUMEN
In this talk I will present two large optical photometric surveys, J-PLUS and J-PAS, carried out at the OAJ observatory, a dedicated facility in continental Spain. J-PLUS, which has already observed few hundreds of square degrees, is scanning the sky with twelve filters, a carefully chosen mix of broad- and narrow-band filters able to capture unique spectral features. I will present the first science verification results, from the IFU-like analysis of local galaxies, to high-redshift emission galaxies and quasars and the detection of metal-poor stars. I will then present forecasts for the J-PAS survey, which will start at the end of this year to observe thousands of square degrees with 54 narrow-band filters covering the entire optical range. Its high spectro-photometric resolution, the wide area covered and the unprecedented depth, will make J-PAS a very powerful tool to unbiasedly study stellar populations, the diversity of galaxies across cosmic time and perform cosmological experiments.
