Forecasting the constraints on optical selection bias and projection effects of galaxy cluster lensing with multiwavelength data
Conghao Zhou, Hao-Yi Wu, Andrés N. Salcedo +12
Galaxy clusters identified with optical imaging tend to suffer from projection effects, which impact richness (the number of member galaxies in a cluster) and lensing coherently. P…
Galaxy Clusters Discovered via the Thermal Sunyaev-Zel'dovich Effect in the 500-square-degree SPTpol Survey
L. E. Bleem, M. Klein, T. M. C. Abbott +125
We present a catalog of 689 galaxy cluster candidates detected at significance via their thermal Sunyaev-Zel'dovich (SZ) effect signature in 95 and 150 GHz data from the 500-…
SPT-SZ MCMF: An extension of the SPT-SZ catalog over the DES region
M. Klein, J. J. Mohr, S. Bocquet +104
We present an extension to a Sunyaev-Zel'dovich Effect (SZE) selected cluster catalog based on observations from the South Pole Telescope (SPT); this catalog extends to lower signa…
SPT Clusters with DES and HST Weak Lensing. I. Cluster Lensing and Bayesian Population Modeling of Multi-Wavelength Cluster Datasets
S. Bocquet, S. Grandis, L. E. Bleem +130
We present a Bayesian population modeling method to analyze the abundance of galaxy clusters identified by the South Pole Telescope (SPT) with a simultaneous mass calibration using…
Cosmological shocks around galaxy clusters: A coherent investigation with DES, SPT & ACT
D. Anbajagane, C. Chang, E. J. Baxter +111
We search for signatures of cosmological shocks in gas pressure profiles of galaxy clusters using the cluster catalogs from three surveys: the Dark Energy Survey (DES) Year 3, the…
Determining the Baryon Impact on the Matter Power Spectrum with Galaxy Clusters
Sebastian Grandis, Giovanni Arico', Aurel Schneider +1
The redistribution of baryonic matter in massive halos through processes like active galactic nuclei feedback and star formation leads to a suppression of the matter power spectrum…
The eROSITA Final Equatorial-Depth Survey (eFEDS): A Machine Learning Approach to Infer Galaxy Cluster Masses from eROSITA X-ray Images
Sven Krippendorf, Nicolas Baron Perez, Esra Bulbul +15
We develop a neural network based pipeline to estimate masses of galaxy clusters with a known redshift directly from photon information in X-rays. Our neural networks are trained u…
The X-ray invisible Universe. A look into the halos undetected by eROSITA
P. Popesso, A. Biviano, E. Bulbul +15
The paper presents the analysis of optically selected GAMA groups and clusters in the SRG/eROSITA X-ray map of eFEDS (eROSITA Final Equatorial Depth Survey), in the halo mass range…
The eROSITA Final Equatorial-Depth Survey (eFEDS) -- Splashback radius of X-ray galaxy clusters using galaxies from HSC survey
Divya Rana, Surhud More, Hironao Miyatake +6
We present the splashback radius measurements around the SRG/eROSITA eFEDS X-ray selected galaxy clusters by cross-correlating them with HSC S19A photometric galaxies. The X-ray se…
