An HI+radio continuum study of local cluster galaxies: Intercepting the early stages of environmental processing with MeerKAT

Alessandro Ignesti, Paolo Serra, Alessandro Bianchetti +14

The evolution of galaxies in clusters is driven by their interaction with the environment, which deeply affects and alters the properties of the multi-phase interstellar medium. He…

The MeerKAT Fornax Survey VII. Characterisation of the Fornax cluster's magnetic field and new insights on magnetisation in large scale systems

Francesca Loi, Matteo Murgia, Federica Govoni +5

Large scale magnetic fields in galaxy clusters can influence their physics and the evolution of the cluster galaxies. These properties remain poorly constrained due to a historical…

First Sardinia Radio Telescope detection of the Sunyaev-Zel'dovich effect at 18.6 GHz

S. Cocchi, F. Loi, M. Murgia +5

Galaxy clusters imprint a distinctive signature on the cosmic microwave background through the thermal Sunyaev-Zel'dovich (SZ) effect, which enables to study the intracluster plasm…

The supersonic nature of jellyfish galaxies

Alessandro Ignesti, Francesca Loi, Antonino Marasco +20

All gas-rich galaxies in cluster environments are expected to experience ram-pressure stripping from the intra-cluster medium. However, only a fraction of these develop ongoing sta…

MEDUSA I. Tracing magnetic field structures in tidal arms of the dwarf-dwarf merger NGC 1487

Sam Taziaux, Aritra Basu, Samata Das +11

Dwarf galaxies are important laboratories for studying cosmic magnetism because they can maintain strong magnetic fields via the action of turbulent dynamo despite their low mass a…

Constraining the magnetic field in the galaxy cluster Abell 2142 using MeerKAT L-band polarisation data

A. Pagliotta, C. J. Riseley, A. Bonafede +2

Magnetic fields permeate the Universe, including galaxy clusters, and affect the thermodynamical properties of the intra-cluster medium (ICM). Cosmological simulations predict that…

A 'MeerKAT-meets-LOFAR' study of the complex multi-component (mini-)halo in the extreme sloshing cluster Abell 2142

C. J. Riseley, A. Bonafede, L. Bruno +7

Clusters of galaxies are turbulent environments, whether merging systems with a turbulent intracluster medium (ICM) or relaxed systems sloshing within the potential well. In many s…
