CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev-Zel'dovich-selected galaxy clusters

Keiichi Umetsu, Raphael Gavazzi, Mauro Sereno +20

We present a weak-lensing shear analysis of 41 Planck SZ-selected galaxy clusters at from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/Meg…

Clusters Hiding Under Millimeter Sources (CHUMS) I: Extreme CHUMS

Harshda Saxena, Adam B. Mantz, Jack Sayers +2

Galaxy cluster abundance provides a powerful probe of the CDM model and enables precise constraints on cosmological parameters. Millimeter-wavelength surveys detect clusters thr…

Intracluster Medium Fluctuations on Scales up to 1 Mpc: A Combined eROSITA and SPT/Planck Analysis of Abell 3266

H. Saxena, A. Heinrich, J. Sayers +22

Galaxy clusters form through hierarchical assembly, where smaller substructures merge to build the largest gravitationally bound objects in the universe. These mergers, combined wi…

CHEX-MATE: Relationship between X-ray and millimetre inferences of galaxy cluster temperature profiles

F. De Luca, H. Bourdin, P. Mazzotta +25

Thermodynamic profiles from X-ray and millimetre observations of galaxy clusters are often compared under the simplifying assumptions of smooth, spherically symmetric intracluster…

CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction

M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31

In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…

CHEX-MATE: The Impact of Triaxiality and Orientation on Planck SZ Cluster Selection and Weak Lensing Mass Measurements

H. Saxena, J. Sayers, A. Gavidia +17

Galaxy cluster abundance measurements are a valuable tool for constraining cosmological parameters like the mass density () and density fluctuation amplitude (). Wide are…

CHEX-MATE: Multi-probe analysis of Abell 1689

L. Chappuis, D. Eckert, M. Sereno +25

The nature of the elusive dark matter can be probed by comparing the predictions of the cold dark matter framework with the gravitational field of massive galaxy clusters. However,…

Kinetic field theory: effects of modified gravity theories with screening mechanisms on non-linear cosmic density fluctuations

Alexander Oestreicher, Harshda Saxena, Niklas Reinhardt +3

In a mean-field approximation within Kinetic Field Theory, it is possible to derive an accurate analytic expression for the power spectrum of present-day non-linear cosmic density…
