Measuring the ICM velocity structure within the A3266 galaxy cluster
E. Gatuzz, J. Sanders, A. Liu +7
We present a detailed analysis of the velocity structure of the hot intracluster medium (ICM) within the A3266 galaxy cluster, including new observations taken between June and Nov…
Mitigating calibration errors from mutual coupling with time-domain filtering of 21 cm cosmological radio observations
N. Charles, N. S. Kern, R. Pascua +80
The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). This has led to the construction of low-frequency radio i…
Investigating Mutual Coupling in the Hydrogen Epoch of Reionization Array and Mitigating its Effects on the 21-cm Power Spectrum
E. Rath, R. Pascua, A. T. Josaitis +78
Interferometric experiments designed to detect the highly redshifted 21-cm signal from neutral hydrogen are producing increasingly stringent constraints on the 21-cm power spectrum…
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: Exploring halo assembly bias with X-ray selected superclusters
A. Liu, E. Bulbul, T. Shin +15
We explore halo assembly bias on cluster scales using large samples of superclusters. Leveraging the largest-ever X-ray galaxy cluster and supercluster samples obtained from the fi…
The Galaxy Group Merger Origin of the Cloverleaf Odd Radio Circle System
E. Bulbul, X. Zhang, M. Kluge +14
Odd radio circles (ORCs) are a newly discovered class of extended faint radio sources of unknown origin. We report the first detection of diffuse X-ray gas at the location of a low…
The SRG/eROSITA All-Sky Survey: Tracing the Large-Scale Structure with a clustering study of galaxy clusters
R. Seppi, J. Comparat, V. Ghirardini +16
The spatial distribution of galaxy clusters provides a reliable tracer of the large-scale distribution of matter in the Universe. The clustering signal depends on intrinsic cluster…
The SRG-eROSITA All-Sky Survey : Constraints on f(R) Gravity from Cluster Abundance
E. Artis, V. Ghirardini, E. Bulbul +28
The evolution of the cluster mass function traces the growth of the linear density perturbations and can be utilized for constraining the parameters of cosmological and alternative…
The SRG/eROSITA All-Sky Survey: X-ray selection function models for the eRASS1 galaxy cluster cosmology
N. Clerc, J. Comparat, R. Seppi +17
Characterising galaxy cluster populations from catalog of sources selected in astronomical surveys requires knowledge of sample incompleteness, known as selection function. The fir…
The SRG/eROSITA All-Sky Survey: Dark Energy Survey Year 3 Weak Gravitational Lensing by eRASS1 selected Galaxy Clusters
S. Grandis, V. Ghirardini, S. Bocquet +119
Number counts of galaxy clusters across redshift are a powerful cosmological probe, if a precise and accurate reconstruction of the underlying mass distribution is performed -- a 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…
