Abstract:
Galaxy clusters are an essential tool to understand and constrain the
cosmological parameters of our Universe. Thanks to its multi-band
design, J-PAS offers a unique group and cluster detection window using
precise photometric redshifts and sufficient depths.
We produce galaxy cluster catalogues from the miniJPAS, which is a
pathfinder survey for the wider J-PAS survey, using the PZWav
algorithm.
Relying only on photometric information, we provide optical mass
tracers for the identified clusters, including richness, optical
luminosity, and stellar mass. By reanalysing the Chandra mosaic of the
AEGIS field, alongside the overlapping XMM-Newton observations, we
produce an X-ray catalogue.
The analysis reveals the possible presence of structures with masses
of 4x1013M☉ at redshift 0.75, highlighting the depth of the
survey. Comparing results with those from two other cluster
catalogues, provided by AMICO and VT, we find 43 common clusters with
cluster centre offsets of 100±60kpc and redshift differences below
0.001. We provide a comparison of the cluster catalogues with a
catalogue of massive galaxies and report on the significance of
cluster selection. In general, we are able to recover approximately
75% of the galaxies with M*>2x1011M☉.
This study emphasises the potential of the J-PAS survey and the
employed techniques down to the group scales.
Description:
We present the galaxy groups and clusters produced by the PZWav and VT
algorithms, applied to the miniJPAS data. AMICO catalogue and
sub-products can be found at
https://www.j-pas.org/ancillarydata/minijpas_amico_galaxy_clusters.
The miniJPAS survey covers an area of 1 deg2, with the same 54
narrow band plus 2 broader band near-UV and near-IR filters
anticipated for the full J-PAS survey. The cluster sample is
accompanied by the galaxy catalogue listing the cluster members (with
probabilistic associations) for two different magnitude ranges, which
ensures completeness up to z=0.3 (-19), and z=0.8 (-21). Due to the
overlapping area with the AEGIS field, we also include an X-ray based
catalogue produced by reanalysing the Chandra mosaic and XMM-Newton
observations.
