The First SRG/eROSITA All-Sky Survey. Characterization of clusters of galaxies misclassified in the eRASS1 point source catalog
F. Balzer, E. Bulbul, M. Kluge +20
The detection of the extended X-ray-emission of the intracluster medium by the first SRG/eROSITA All-Sky Survey (eRASS1), combined with optical and near-infrared follow-up, resulte…
The Galaxy Group Merger Origin of the Cloverleaf Odd Radio Circle System
E. Bulbul, X. Zhang, M. Kluge +14
Odd radio circles (ORCs) are a newly discovered class of extended faint radio sources of unknown origin. We report the first detection of diffuse X-ray gas at the location of a low…
The XXL Survey XLV. Linking the ages of optically selected groups to their X-ray emission
J. P. Crossett, S. L. McGee, T. J. Ponman +16
We investigate the properties of 232 optical spectroscopically selected groups from the Galaxy And Mass Assembly (GAMA) survey that overlap the XXL X-ray cluster survey. X-ray aper…
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.…
Projection effects in galaxy cluster samples: insights from X-ray redshifts
M. E. Ramos-Ceja, F. Pacaud, T. H. Reiprich +3
Up to now, the largest sample of galaxy clusters selected in X-rays comes from the ROSAT All-Sky Survey (RASS). Although there have been many interesting clusters discovered with t…
The XXL survey XXXV. The role of cluster mass in AGN activity
E. Koulouridis, M. Ricci, P. Giles +15
We present the results of a study of the AGN density in a homogeneous and well-studied sample of 167 bona fide X-ray galaxy clusters () from the XXL Survey. The results…
The XXL Survey: XXXIII. Chandra Constraints on the AGN Contamination of z > 1 XXL Galaxy Clusters
C. H. A. Logan, B. J. Maughan, M. N. Bremer +11
Context. The XMM-XXL survey uses observations from XMM-Newton to detect clusters of galaxies over a wide range in mass and redshift. The moderate PSF of XMM-Newton means that point…
The XXL Survey: XXXIV. Double irony in XXL-North. A tale of two radio galaxies in a supercluster at z = 0.14
C. Horellou, H. T. Intema, V. Smolčić +21
We show how the XXL multiwavelength survey can be used to shed light on radio galaxies and their environment. Two prominent radio galaxies were identified in a visual examination o…
The XXL Survey: IX. Optical overdensity and radio continuum analysis of a supercluster at
N. Baran, V. Smolčić, D. Milaković +18
We present observations with the Karl G. Jansky Very Large Array (VLA) at 3 GHz toward a sub-field of the XXL-North 25 deg field targeting the first supercluster discovered i…
The XXL Survey: VI. The 1000 brightest X-ray point sources
S. Fotopoulou, F. Pacaud, S. Paltani +36
X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). The XXL Survey spans two fields of a combined 50 $…
