TL;DR
This paper presents a new galaxy cluster catalogue from the S-PLUS survey using the PzWav detection algorithm, demonstrating high purity and completeness, and validating its effectiveness against known clusters.
Contribution
The paper introduces the PzWav algorithm for galaxy cluster detection in multi-filter photometric data, achieving high accuracy and validating it with simulations and known cluster samples.
Findings
80% purity and completeness at S/N>3.3 for clusters with M_{200} > 10^{14} M_00.
Positional and redshift accuracy with scatter of 12 kpc and 8.8e-3, respectively.
Recovers ~80% of known X-ray and SZ clusters, validating the method.
Abstract
We present a catalogue of 4499 groups and clusters of galaxies from the first data release of the multi-filter (5 broad, 7 narrow) Southern Photometric Local Universe Survey (S-PLUS). These groups and clusters are distributed over 273 deg in the Stripe 82 region. They are found using the PzWav algorithm, which identifies peaks in galaxy density maps that have been smoothed by a cluster scale difference-of-Gaussians kernel to isolate clusters and groups. Using a simulation-based mock catalogue, we estimate the purity and completeness of cluster detections: at S/N>3.3 we define a catalogue that is 80% pure and complete in the redshift range 0.1<z<0.4, for clusters with M. We also assessed the accuracy of the catalogue in terms of central positions and redshifts, finding scatter of kpc and , respectively. Moreover,…
