MeerKAT observations detect radio halos in 27% of 30 massive clusters at z>1, a rate lower than at intermediate redshifts but above model predictions, with power-mass scaling similar to lower-z samples.

Galaxy clusters have an average projected ellipticity of 0.310 with axis ratio 0.527, showing no significant mass or redshift dependence, measured via weak lensing on DES Y3 data and verified with mocks.
LEGGOS presents a uniform framework that jointly models lensing, photometry, and integral-field spectroscopy to disentangle stellar populations in clumps of high-redshift lensed galaxies.
PSZ is a new meta-catalogue of 1500 confirmed Planck SZ clusters incorporating 281 new confirmations, 262 invalidations, updated redshifts for 552 clusters, and homogeneously derived masses corrected for selection effects.
ComPACT is a new SZ-selected galaxy cluster catalogue from CNN analysis of ACT+Planck data with 2,962 candidates, ~60% confirmation, 116 new redshifts, 158 new masses, and five new massive clusters at z>0.7 that increase the known high-mass high-z population by ~10%.
A new 296-detector 90 GHz TES bolometer array for CLASS achieves uniform properties, 16 μK√s NET, 0.37 optical efficiency, and a 41% mapping speed boost after addressing blue-leak radiation.
The SKA will enable high-resolution, high-sensitivity observations of the thermal SZ effect in massive halos, capturing both pressure substructures and large-scale ICM emission.

The MeerKAT Massive Distant Clusters Survey: a search for diffuse radio emission in 30 massive SZ-selected clusters at $z > 1$
MeerKAT observations detect radio halos in 27% of 30 massive clusters at z>1, a rate lower than at intermediate redshifts but above model predictions, with power-mass scaling similar to lower-z samples.
