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…
Hydrostatic Mass Profiles of Galaxy Clusters in the eROSITA Survey
Dominik Scheck, Jeremy S. Sanders, Veronica Biffi +3
To assume hydrostatic equilibrium between the intracluster medium and the gravitational potential of galaxy clusters is an extensively used method to investigate their total masses…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray Properties and Scaling Relations of Galaxy Clusters and Groups
Y. Emre Bahar, Esra Bulbul, Nicolas Clerc +16
We investigate the scaling relations between X-ray observables of the clusters detected in the eFEDS field using Spectrum-Roentgen-Gamma/eROSITA observations taking into account th…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray Observable-to-Mass-and-Redshift Relations of Galaxy Clusters and Groups with Weak-Lensing Mass Calibration from the Hyper Suprime-Cam Subaru Strategic Program Survey
I-Non Chiu, Vittorio Ghirardini, Ang Liu +18
We present the first weak-lensing mass calibration and X-ray scaling relations of galaxy clusters and groups selected in the Final Equatorial Depth Survey (eFEDS) observe…
The eROSITA view of the Abell 3391/95 field: The Northern Clump. The largest infalling structure in the longest known gas filament observed with eROSITA, XMM-Newton, and Chandra
Angie Veronica, Yuanyuan Su, Veronica Biffi +18
SRG/eROSITA PV observations revealed the A3391/95 cluster system and the Northern Clump (MCXC J0621.7-5242 galaxy cluster) are aligning along a cosmic filament in soft X-rays, simi…
Spatial Distribution of Metals in the ICM: Evolution of the Iron Excess in Relaxed Galaxy Clusters
Ang Liu, Paolo Tozzi, Heng Yu +2
We investigate the spatial distribution of iron in the intra-cluster medium in a selected sample of 41 relaxed clusters in the redshift range using {\sl Chandra}…
Searching for bulk motions in the ICM of massive, merging clusters with Chandra CCD data
Ang Liu, Heng Yu, Paolo Tozzi +1
We search for bulk motions in the intracluster medium (ICM) of massive clusters showing evidence of an ongoing or recent major merger with spatially resolved spectroscopy in {\sl C…
A method to search for bulk motions in the ICM with {\sl Chandra} CCD spectra: application to the Bullet cluster
Ang Liu, Heng Yu, Paolo Tozzi +1
We propose a strategy to search for bulk motions in the intracluster medium (ICM) of merging clusters based on {\sl Chandra} CCD data. Our goal is to derive robust measurements of…
