The SRG/eROSITA All-Sky Survey: Early dark energy and Hubble constant from the cluster mass function
J. Strunk, E. Artis, E. Bulbul +23
The evolution of the mass function of massive galaxy clusters is a well-established probe of cosmology. Using the eROSITA X-ray instrument on board the Spectrum Roentgen Gamma (SRG…
Weak-lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: III. A precision cosmological sample enabled by optical confirmation
I-Non Chiu, Kai-Feng Chen, Masamune Oguri +9
We develop fCAMIRA (forced-mode CAMIRA), a tool for optical cluster confirmation, and apply it to a sample of 129 weak-lensing (WL) shear-selected galaxy clusters identified in ape…
XMM-Newton observations of ten high-redshift CAMIRA clusters of galaxies
Naomi Ota, Ikuyuki Mitsuishi, Nobuhiro Okabe +9
We present results from XMM-Newton observations of ten high-redshift () galaxy clusters selected from the CAMIRA catalog based on high richness (). These m…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray stacking analysis of Subaru's optically selected clusters spanning low richness regime
N. T. Nguyen-Dang, N. Ota, N. Okabe +17
This is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the SRG/eROS…
The SRG/eROSITA All-Sky Survey : Constraints on the structure growth from cluster number counts
E. Artis, E. Bulbul, S. Grandis +29
Beyond testing the current cosmological paradigm, cluster number counts can also be utilized to investigate the discrepancies currently affecting current cosmological measurements.…
Peaks in weak lensing mass maps for cluster astrophysics and cosmology
Masamune Oguri, Satoshi Miyazaki
Clusters of galaxies can be identified from peaks in weak lensing aperture mass maps constructed from weak lensing shear catalogs. Such purely gravitational cluster selection consi…
Weak-Lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: II. Cosmological Constraints from the Cluster Abundance
I-Non Chiu, Kai-Feng Chen, Masamune Oguri +9
We present cosmological constraints using the abundance of weak-lensing shear-selected galaxy clusters in the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The clusters are sel…
Weak-Lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: I. Cluster Catalog, Selection Function and Mass--Observable Relation
Kai-Feng Chen, I-Non Chiu, Masamune Oguri +9
We present the first step toward deriving cosmological constraints through the abundances of galaxy clusters selected in a weak-lensing aperture mass map, con…
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: Weak-Lensing of eRASS1 Galaxy Clusters in KiDS-1000 and Consistency Checks with DES Y3 & HSC-Y3
Florian Kleinebreil, Sebastian Grandis, Tim Schrabback +21
We aim to participate in the calibration of the X-ray photon count rate to halo mass scaling relation of galaxy clusters selected in the first eROSITA All-Sky Survey on the Western…
The SRG/eROSITA all-sky survey: Cosmology constraints from cluster abundances in the western Galactic hemisphere
V. Ghirardini, E. Bulbul, E. Artis +46
The cluster mass function traces the growth of linear density perturbations and provides valuable insights into the growth of structures, the nature of dark matter, and the cosmolo…
