Ancillary data

This section gathers a collection of ancillary data that complements the J-PLUS photometric images and catalogues presented here. This ancillary data can be based on a particular analysis of J-PLUS images, so will not be accessible as Value Added Catalogues in the ADQL database. This includes, for example, the detailed photometric study of large, nearby galaxies or the construction of galaxy mocks.

The spatial distribution of galaxies in a thin angular slice (1 deg) inside our mock lightcone.  Each galaxy with M<sub>stellar</sub> > 10<sup>10</sup> M<sub>⊙</sub>/h is shown as a black dot.

Photometric surveys have been important in establishing our current understanding of how galaxies were formed and evolve. Synthetic galaxy catalogues are crucial to optimally exploit their data, in particular for the case of photometric surveys that combine broad-band and narrow-band filters. J-PLUS has the unique feature of combining 5 broad and 7 medium band filters, tailored mocks have been built to help to exploit all the information contained in the data.
