Offset between X-ray and optical centers in clusters of galaxies: connecting eROSITA data and simulations
R. Seppi, J. Comparat, K. Nandra +6
The characterization of the dynamical state of clusters is key to study their evolution, their selection, and use them as a cosmological probe. The offsets between different defini…
X-ray analysis of JWST's first galaxy cluster lens SMACS J0723.3-7327
A. Liu, E. Bulbul, M. E. Ramos-Ceja +10
SMACS~J0723.3-7327 is the first galaxy cluster lens observed by JWST. Based on the ERO data from JWST, several groups have reported the results on strong lensing analysis and mass…
A MUSE view of the massive merging galaxy cluster ACT-CL J0102-4915 (El Gordo) at z = 0.87: robust strong lensing model and data release
G. B. Caminha, C. Grillo, P. Rosati +11
We present a detailed strong lensing analysis of the massive and distant () galaxy cluster ACT-CL J01024915 (ACT0102, also known as El Gordo), taking advantage of new s…
Detecting clusters of galaxies and active galactic nuclei in an eROSITA all-sky survey digital twin
R. Seppi, J. Comparat, E. Bulbul +15
The extended ROentgen Survey with an Imaging Telescope Array (eROSITA) onboard the Spectrum-Roentgen-Gamma (SRG) observatory is revolutionizing X-ray astronomy. It provides large s…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray properties of Subaru optically-selected clusters
N. Ota, N. T. Nguyen-Dang, I. Mitsuishi +17
We present the results of a systematic X-ray analysis of optically rich galaxy clusters detected by the Subaru HSC survey in the eROSITA eFEDS field. Through a joint analysis of SR…
The 700 ks Chandra Spiderweb Field I: evidence for widespread nuclear activity in the Protocluster
P. Tozzi, L. Pentericci, R. Gilli +21
(Abridged) We present an analysis of the 700 ks Chandra ACIS-S observation of the field around the Spiderweb Galaxy at z=2.156, focusing on the nuclear activity in the associated l…
