The MeerKAT Massive Distant Clusters Survey: a search for diffuse radio emission in 30 massive SZ-selected clusters at

Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +10

We present the results of a search for diffuse radio emission in a uniformly selected sample of 30 of the most massive Sunyaev-Zel'dovich selected galaxy clusters at , provi…

The MeerKAT Massive Distant Clusters Survey: detection of diffuse radio emission in galaxy clusters at

Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +11

Diffuse, low surface-brightness radio emission in merging galaxy clusters provides insights into cosmic structure formation, the growth of magnetic fields, and turbulence. This pap…

The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect

Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38

The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…

ICM-SHOX III. The case of MACS J0018.5+1626, a radio relic that looks like a radio halo?

P. Domínguez-Fernández, P. Domínguez-Fernández, J. A. ZuHone +10

We present the first detailed numerical modeling of the radio emission from MACS J0018.5+1626 as part of the Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Op…

Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT

Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +58

The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-…

The thermodynamic structure and large-scale structure filament in MACS J0717.5+3745

J. P. Breuer, N. Werner, T. Plšek +12

We present the results of Chandra and XMM-Newton X-ray imaging and spatially resolved spectroscopy, as well as new MUSTANG2 90 GHz observations of the thermal Sunyaev-Zeldovich eff…
