Ancillary data
This section gathers a collection of ancillary data that complements the J-PAS photometric images and catalogues presented here. This ancillary data can be based on a particular analysis of J-PAS images, so sometimes it can not be accessible as Value Added Catalogues in the ADQL database.
In the background, the response of AMICO to the presence of galaxy clusters for a redshift slice z=0.24. In the top right and bottom left boxes the optical images of the miniJ-PAS data of two clusters together with the isocontours displaying the X-ray emission measured with Chandra. The top left box shows another detected cluster laying at a higher redshift, z=0.36 well disentangled by the foreground structures.
Samples of galaxy clusters disclose the physics at play in galaxy formation and allows to constrain cosmological models once their mass, position (for clustering studies) and redshift are known. Within this context, large optical data sets play a crucial role. We present the galaxy groups and clusters based on the mini-JPAS data and the AMICO algorithm (Adaptive Matched Identifier of Clustered Objects).
