Baryonification IV: Constraining baryonic feedback with X-ray gas fractions
Jozef Bucko, Andrina Nicola, Aurel Schneider +8
Baryonic feedback redistributes gas around dark matter halos, suppressing the matter power spectrum at scales now probed by weak lensing surveys. X-ray observations directly trace…

The SRG/eROSITA all-sky survey: X-ray scaling relations of galaxy groups and clusters in the western Galactic hemisphere
M. E. Ramos-Ceja, L. Fiorino, E. Bulbul +19
The soft X-ray telescope on board the SRG mission, eROSITA, has produced the largest sample to date of galaxy groups and clusters detected via their intracluster and intragroup med…
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…
The SRG/eROSITA All-Sky Survey -Band Follow-Up Observations for Selected High-Redshift Galaxy Cluster Candidates

We select galaxy cluster candidates from the high-redshift (BEST_Z > 0.9) end of the first SRG/eROSITA All-Sky Survey (eRASS1) galaxy cluster catalogue, for which we obtain moderat…
The SRG/eROSITA All-Sky Survey. Detection of shock-heated gas beyond the halo boundary into the accretion region
X. Zhang, E. Bulbul, B. Diemer +16
The hot gas in the outskirts of galaxy cluster-sized halos, extending around and beyond the virial radius into nearby accretion regions, remains among one of the least explored bar…
The SRG/eROSITA All-Sky Survey. The Weak-Lensing Mass Calibration and the Stellar Mass-to-Halo Mass Relation from the Hyper Suprime-Cam Subaru Strategic Program
I-Non Chiu, Vittorio Ghirardini, Sebastian Grandis +23
We present the weak-lensing mass calibration and constrain the BCG (brightest cluster galaxy) stellar-mass-to-halo-mass-and-redshift () relation for a s…
eROSITA clusters dynamical state and their impact on the BCG luminosity
A. Zenteno, M. Kluge, R. Kharkrang +30
The Spectrum Roentgen Gamma/eROSITA first public release contains 12,247 clusters and groups. We use the offset between the Brightest Cluster Galaxy (BCG) and the X--ray peak (D$_{…
The Three Hundred: Gas Properties Outside of Galaxy Cluster with the WHIM Contribution and Detection
Renjie Li, Weiguang Cui, Ang Liu +4
We investigate the physical properties and detectability of warm-hot intergalactic medium (WHIM) gas with temperatures in the range K around galaxy clusters using simu…
The SRG/eROSITA All-Sky Survey : Subaru/HSC-SSP weak-lensing mass measurements for the eRASS1 Galaxy Clusters
Nobuhiro Okabe, Thomas H. Reiprich, Sebastian Grandis +20
We performed individual weak-lensing (WL) mass measurements for 78 eROSITA's first All-Sky Survey (eRASS1) clusters in the footprint of Hyper Suprime-Cam Subaru Strategic Program (…
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: The morphologies of clusters of galaxies I: A catalogue of morphological parameters
J. S. Sanders, Y. E. Bahar, E. Bulbul +10
The first SRG/eROSITA all-sky X-ray survey, eRASS1, resulted in a catalogue of over twelve thousand optically-confirmed galaxy groups and clusters in the western Galactic hemispher…
Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters
Pengfei Li, Ang Liu, Matthias Kluge +13
The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…
The SRG/eROSITA All-Sky Survey : Constraints on the structure growth from cluster number counts
