Probing the baryonic--dark matter connection in galaxy clusters using X-rays with gated recurrent unit neural networks
Asif Iqbal, Subhabrata Majumdar, Weiguang Cui +3
Accurate cluster mass measurements are crucial for cosmology, yet conventional hydrostatic equilibrium (HSE) methods can suffer from systematic biases, particularly in dynamically…
The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
The paper presents MeerKAT multi‑frequency and polarimetric observations of the merging galaxy cluster Abell 2034, confirming a radio halo, identifying a relic and steep‑spectrum f…
Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
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…
Euclid Quick Data Release (Q1): The geometry of dark matter halos from extragalactic streams
Euclid Collaboration, N. Starkman, J. Nibauer +295
Wide-field surveys like Euclid mark a new era of extragalactic stellar stream studies. With a large number of streams, it is now possible to constrain the dark matter halos of gala…
PSZ: The meta-catalogue of Planck Sunyaev-Zeldovich sources
P. TarrÃo, M. Arnaud, J. -B. Melin +2
We present the PSZ, a meta-catalogue of 1962 clusters and cluster candidates produced by the Planck Collaboration. The PSZ contains fully-updated validation information for all off…
