The unusually weak and exceptionally steep radio relic in Abell 2108
Gerrit Schellenberger, Simona Giacintucci, Lorenzo Lovisari +9
Mergers between galaxy clusters often drive shocks into the intra cluster medium (ICM), the effects of which are sometimes visible via temperature and density jumps in the X-ray, a…
HSC-XXL : Baryon budget of the 136 XXL Groups and Clusters
Daichi Akino, Dominique Eckert, Nobuhiro Okabe +17
We present our determination of the baryon budget for an X-ray-selected XXL sample of 136 galaxy groups and clusters spanning nearly two orders of magnitude in mass ($M_{500}\sim 1…
The XXL survey: XLVI. Forward cosmological analysis of the C1 cluster sample
Christian Garrel, Marguerite Pierre, Patrick Valageas +15
We present the forward cosmological analysis of an selected sample of galaxy clusters out to a redshift of unity. Following our previous 2018 study based on the dn/dz quantit…
The thermalisation of massive galaxy clusters
Mauro Sereno, Lorenzo Lovisari, Weiguang Cui +1
In the hierarchical scenario of structure formation, galaxy clusters are the ultimate virialised products in mass and time. Hot baryons in the intracluster medium (ICM) and cold ba…
AMICO galaxy clusters in KiDS-DR3: the impact of estimator statistics on the luminosity-mass scaling relation
Merijn Smit, Andrej Dvornik, Mario Radovich +4
As modern-day precision cosmology aims for statistical uncertainties of the percent level or lower, it becomes increasingly important to reconsider estimator assumptions at each st…
Understanding X-ray and optical selection of galaxy clusters: A comparison of the XXL and CAMIRA cluster catalogues obtained in the common XXL-HSC SSP area
J. P. Willis, M. Oguri, M. E. Ramos-Ceja +31
Large samples of galaxy clusters provide knowledge of both astrophysics in the most massive virialised environments and the properties of the cosmological model that defines our Un…
Cosmological Constraints from Galaxy Cluster Sparsity, Cluster Gas Mass Fraction and Baryon Acoustic Oscillations Data
P. S. Corasaniti, M. Sereno, S. Ettori
In recent years, the availability of large, complete cluster samples has enabled numerous cosmological parameter inference analyses using cluster number counts. These have provided…
AMICO galaxy clusters in KiDS-DR3: cosmological constraints from large-scale stacked weak lensing profiles
Carlo Giocoli, Federico Marulli, Lauro Moscardini +15
Context. The large-scale mass distribution around dark matter haloes hosting galaxy clusters provides sensitive cosmological information. Aims. In this work, we make use of a large…
The Lack of Non-Thermal Motions in Galaxy Cluster Cores
Jack Sayers, Mauro Sereno, Stefano Ettori +5
We report the non-thermal pressure fraction (Pnt/Ptot) obtained from a three-dimensional triaxial analysis of 16 galaxy clusters in the CLASH sample using gravitational lensing (GL…
Morphology of relaxed and merging galaxy clusters. Analytical models for monolithic Minkowski functionals
C. Schimd, M. Sereno
Galaxy clusters exhibit a rich morphology during the early and intermediate stages of mass assembly, especially beyond their boundary. A classification scheme based on shapefinders…
