A study of the large-scale formation in the environment of A3266: Infalling groups, filaments, and a premerger cold front
J. Dietl, A. Veronica, T. H. Reiprich +7
Abell 3266 (A3266) is a dynamically active galaxy cluster embedded in a dense environment of galaxy groups and clusters at similar redshift. Data from the Spektrum Roentgen Gamma (…
The Quiescent Sloshing Core of Abell 496 with XRISM
Angie Veronica, Thomas H. Reiprich, Naomi Ota +9
Gas motions provide insight into the dynamical history and physical processes within galaxy clusters. We investigate the kinematics of the ICM in the core of A496, a nearby, X-ray…
Bulk and turbulent gas motions in the interacting galaxy cluster Abell 3395 South observed with XRISM
Naomi Ota, Angie Veronica, Jakob Dietl +8
We investigate the gas motions in the core region of the Abell~3395 South subcluster (A3395S) using high-resolution X-ray spectroscopy with XRISM/Resolve. By analyzing the Fe~XXV H…
The SRG/eROSITA All-Sky Survey: A comprehensive X-ray analysis of the Hydra I galaxy cluster
Alpish Srivastava, Thomas H. Reiprich, Angie Veronica +4
The Hydra I galaxy cluster (Abell 1060) is a nearby example of a low-temperature cluster that exhibits intermediate cool core and non-cool core properties. Our aims are to extend t…
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: 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…
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…
