Galaxy clusters and groups in eFEDS
Listed in IVOA Registry (Virtual Observatory)
The eROSITA Final Equatorial-Depth Survey has been carried out during the PV phase of the SRG/eROSITA telescope and completed in November 2019.
Description
In the 140 deg2 area covered by eFEDS, 542 candidate clusters and groups are detected as extended X-ray sources, down to a flux of ~10^-14^erg/s/cm2 in the soft band (0.5-2keV) within 1'. We provide the catalog of candidate galaxy clusters and groups in eFEDS.
We perform imaging and spectral analysis on the eFEDS clusters with eROSITA X-ray data, and study the properties of the sample. The clusters are distributed in the redshift range [0.01, 1.3], with the median redshift at 0.35. We obtain the ICM temperature measurement with >2{sigma} c.l. for ~1/5 (102/542) of the sample.

The average temperature of these clusters is ~2keV. Radial profiles of flux, luminosity, electron density, and gas mass are measured from the precise modeling of the imaging data. The selection function, the purity and completeness of the catalog are examined and discussed in detail.
The contamination fraction is ~1/5 in this sample, dominated by misidentified point sources. The X-ray Luminosity Function of the clusters agrees well with the results obtained from other recent X-ray surveys. We also find 19 supercluster candidates in eFEDS.
