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…
H1821+643: The most X-ray and infrared luminous AGN in the Swift/BAT survey in the process of rapid stellar and supermassive black hole mass assembly
Hikaru Fukuchi, Kohei Ichikawa, Masayuki Akiyama +6
H1821+643 is the most X-ray luminous non-beamed AGN of erg s in the Swift/BAT ultra-hard X-ray survey and it is also a hyper-lumin…
The Spiderweb proto-cluster is being magnetized by its central radio jet
Craig S. Anderson, Christopher L. Carilli, Paolo Tozzi +10
We present deep broadband radio polarization observations of the Spiderweb radio galaxy (J1140-2629) in a galaxy proto-cluster at . These yield the most detailed polarimetr…
X-ray Emission and Radio Emission from the Jets and Lobes of the Spiderweb Radio Galaxy
Christopher L. Carilli, Craig S. Anderson, Paolo Tozzi +12
Deep Chandra and VLA imaging reveals a clear correlation between X-ray and radio emission on scales ~kpc in the Spiderweb radio galaxy at z=2.16. The X-ray emission assoc…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Galaxy Clusters and Groups in Disguise
Esra Bulbul, Ang Liu, Thomas Pasini +21
The eROSITA Final Equatorial-Depth Survey (eFEDS), executed during the performance verification phase of the Spectrum-Roentgen-Gamma (SRG)/eROSITA telescope, was completed in Nov.…
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…
Establishing the X-ray Source Detection Strategy for eROSITA with Simulations
Teng Liu, Andrea Merloni, Johan Comparat +25
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) satellite has started to detect new X-ray sources over the full sky at an unprecedented rate. Understanding t…
Systematic search for lensed X-ray sources in the CLASH fields
Ang Liu, Paolo Tozzi, Piero Rosati +8
We search for unresolved X-ray emission from lensed sources in the FOV of 11 CLASH clusters with Chandra data. We consider the solid angle in the lens plane corresponding to a magn…
Local Group Analogs in CDM cosmological simulations
Meng Zhai, Qi Guo, Gang Zhao +2
We use semi-analytic galaxy catalogs based on two high-resolution cosmological -body simulations, Millennium-WMAP7 and Millennium-II, to investigate the formation of the Local G…
Leptogenesis and Dark Matter from Low Scale Seesaw
Ang Liu, Zhi-Long Han, Yi Jin +1
In this paper, we perform a detail analysis on leptogenesis and dark matter form low scale seesaw. In the framework of 2HDM, we further introduce one scalar singlet and one…
Testing the rotation versus merger scenario in the galaxy cluster Abell 2107
Ang Liu, Paolo Tozzi
We search for global rotation of the intracluster medium (ICM) in the galaxy cluster Abell 2107, where previous studies have detected rotational motion in the member galaxies with…
On the origin of central abundance drops in the intracluster medium of galaxy groups and clusters
Ang Liu, Meng Zhai, Paolo Tozzi
A central drop of ICM Fe abundance has been observed in several cool-core clusters. It has been proposed that this abundance drop may be due, at least partially, to the depletion o…
Spatial Distribution of Metals in the ICM: Evolution of the Iron Excess in Relaxed Galaxy Clusters
