The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields
Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35
The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…
XMM-Newton follow-up of a sample of apparent low surface brightness galaxy groups detected in the ROSAT All-Sky Survey
Claudia Spinelli, Angie Veronica, Florian Pacaud +4
Galaxy cluster cosmology relies on complete and pure samples spanning a large range of masses and redshifts. In Xu et al. (2018) and Xu et al. (2022), we discovered an apparently n…
The SRG/eROSITA all-sky survey: View of the Fornax galaxy cluster
T. H. Reiprich, A. Veronica, F. Pacaud +18
The Fornax cluster is one of the closest X-ray-bright galaxy clusters. Previous observations of the intracluster medium were limited to less than R500. We aim to significantly exte…
The SRG/eROSITA all-sky survey. X-ray emission from the warm-hot phase gas in long cosmic filaments
X. Zhang, E. Bulbul, N. Malavasi +24
The properties of the warm-hot intergalactic medium (WHIM) in cosmic filaments are among the least quantified units in modern astrophysics. The Spectrum Roentgen Gamma/eROSITA All…
The SRG/eROSITA All-Sky Survey: Large-scale view of the Centaurus cluster
Angie Veronica, Thomas H. Reiprich, Florian Pacaud +9
Methods. We utilized the combined five SRG/eROSITA All-Sky Survey data (eRASS:5) to perform X-ray imaging and spectral analyses of the Centaurus cluster in various directions to la…
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…
