A "MeerKAT-meets-LOFAR" Study of 2A 0335+096: Discovery of a Complex 500 kpc Radio Halo in a Disturbed Cool-Core Cluster
C. J. Riseley, R. J. van Weeren, L. Lovisari +9
The emerging picture of radio haloes and mini-haloes in galaxy clusters is more blurred and far less distinct than once thought. While both trace cosmic ray electrons and magnetic…

Radio observations of gamma-ray burst afterglows provide insight in to the different emitting regions within the jet, its hydrodynamics and burst environment. In this paper, we pre…
The SKA View of the Sunyaev-Zeldovich Effect from Massive Cosmic Halos
Yvette C. Perrott, Luca Di Mascolo, Rémi Adam +4
The thermal intracluster medium (ICM) can be observed via its interaction with Cosmic Microwave Background photons, known as the Sunyaev-Zeldovich (SZ) effect. This effect produces…

Photometric Redshift Predictions with a Neural Network for DESI Quasars
Jeremy P. Moss, Stephen J. Curran, Yvette C. Perrott
Accurate redshift measurements are essential for studying the evolution of quasi-stellar objects (QSOs) and their role in cosmic structure formation. While spectroscopic redshifts…
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…
Bayesian recalibration of Planck galaxy cluster scaling relations including relativistic Sunyaev-Zel'dovich corrections
Yvette C. Perrott
We investigate the impact of relativistic SZ corrections on Planck measurements of massive galaxy clusters, finding that they have a significant impact at the 5 -- 15% and…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Resolving the Hot and Ionized Universe through the Sunyaev-Zeldovich effect
Luca Di Mascolo, Yvette Perrott, Tony Mroczkowski +23
An omnipresent feature of the multi-phase ``cosmic web'' is that warm/hot (> K) ionized gas pervades it. This gas constitutes a relevant contribution to the overall universal…
A Semi-Parametric Approach to Fitting Gas Pressure Profiles of Galaxy Clusters
Kang Wang, Yvette Perrott, Richard Arnold +1
This study focuses on modelling galaxy cluster gas profiles via a semi-parametric nodal approach. While traditional methods like the generalised Navarro-Frenk-White (gNFW) often en…
Temperature measurements with the relativistic Sunyaev-Zel'dovich effect
Yvette Perrott
At temperatures above ~5 keV, the non-relativistic approximation used to derive the classical thermal Sunyaev-Zel'dovich effect spectrum begins to fail. When relativistic effects a…
