X-ray and optical analysis of the distant, merging double cluster SPT-CLJ2228-5828, its gas bridge, and shock front
K. Migkas, M. W. Sommer, T. Schrabback +15
Galaxy cluster mergers are excellent laboratories for studying a wide variety of different physical phenomena. Such a unique system is the distant SPT-CLJ2228-5828 cluster merger l…
Examining the local Universe isotropy with galaxy cluster velocity dispersion scaling relations
A. Pandya, K. Migkas, T. H. Reiprich +7
In standard cosmology, the late Universe is assumed to be statistically homogeneous and isotropic. However, a recent study based on galaxy clusters by Migkas et al. (2021, arXiv:21…
Galaxy clusters as probes of cosmic isotropy
Konstantinos Migkas
Scaling relations of galaxy clusters are a powerful probe of cosmic isotropy in the late Universe. Owing to their strong cosmological dependence, galaxy cluster scaling relations c…
The SRG/eROSITA All-Sky Survey: First catalog of superclusters in the western Galactic hemisphere
A. Liu, E. Bulbul, M. Kluge +21
Superclusters of galaxies mark the large-scale overdense regions in the Universe. Superclusters provide an ideal environment to study structure formation and to search for the emis…
The SRG/eROSITA All-Sky Survey: The first catalog of galaxy clusters and groups in the Western Galactic Hemisphere
E. Bulbul, A. Liu, M. Kluge +31
Clusters of galaxies can be used as powerful probes to study astrophysical processes on large scales, test theories of the growth of structure, and constrain cosmological models. T…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
A. Merloni, G. Lamer, T. Liu +142
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…
The SRG/eROSITA All-Sky Survey: SRG/eROSITA cross-calibration with Chandra and XMM-Newton using galaxy cluster gas temperatures
K. Migkas, D. Kox, G. Schellenberger +17
Galaxy cluster gas temperatures () play a crucial role in many cosmological and astrophysical studies. However, it has been shown that measurements can vary between differen…
The SRG/eROSITA All-Sky Survey: View of the Virgo Cluster
Hannah McCall, Thomas H. Reiprich, Angie Veronica +11
As the closest galaxy cluster, the Virgo Cluster is an exemplary environment for the study of the large-scale filamentary structure and physical effects that are present in cluster…
Discovery of a >13 Mpc long X-ray filament between two galaxy clusters beyond three times their virial radii
J. Dietl, F. Pacaud, T. H. Reiprich +5
The new Spectrum Roentgen Gamma (SRG) eROSITA X-ray telescope has a superior response to extended soft X-rays, which makes it ideal for studying low X-ray surface brightness emissi…
