Extending empirical constraints on the SZ-mass scaling relation to higher redshifts via HST weak lensing measurements of nine clusters from the SPT-SZ survey at
Hannah Zohren, Tim Schrabback, Sebastian Bocquet +17
We present a Hubble Space Telescope (HST) weak gravitational lensing study of nine distant and massive galaxy clusters with redshifts ($z_\mathrm{medi…
ShapePipe: a new shape measurement pipeline and weak-lensing application to UNIONS/CFIS data
Axel Guinot, Martin Kilbinger, Samuel Farrens +16
UNIONS is an ongoing collaboration that will provide the largest deep photometric survey of the Northern sky in four optical bands to date. As part of this collaboration, CFIS is t…
An X-ray selected catalog of extended galaxy clusters from the ROSAT All-Sky Survey (RXGCC)
Weiwei Xu, Miriam E. Ramos-Ceja, Florian Pacaud +2
There is a known tension between cosmological parameter constraints obtained from the primary CMB and those from galaxy cluster samples. One possible explanation could be certain t…
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…
Studying the merging cluster Abell 3266 with eROSITA
J. S. Sanders, V. Biffi, M. Brüggen +15
Abell 3266 is one of the X-ray brightest galaxy clusters in the sky and is a well-known merging system. Using the ability of the eROSITA telescope onboard SRG (Spectrum Röntgen Gam…
Probing galaxy bias and intergalactic gas pressure with KiDS Galaxies-tSZ-CMB lensing cross-correlations
Ziang Yan, Ludovic van Waerbeke, Tilman Tröster +14
We constrain the redshift dependence of gas pressure bias (bias-weighted average electron pressure), which characterises the thermo…
