Weak lensing measurements of the APEX-SZ galaxy cluster sample
Matthias Klein, Holger Israel, Aarti Nagarajan +5
We present a weak lensing analysis for galaxy clusters from the APEX-SZ survey. For massive galaxy clusters that were observed via the Sunyaev-Zel\textquotesingle dovich effec…
A LOFAR study of non-merging massive galaxy clusters
Federica Savini, Annalisa Bonafede, Marcus Brueggen +15
Centrally located diffuse radio emission has been observed in both merging and non-merging galaxy clusters. Depending on their morphology and size, we distinguish between giant rad…
Discovery of large scale shock fronts correlated with the radio halo and radio relic in the A2163 galaxy cluster
Sophia Thölken, Thomas H. Reiprich, Martin W. Sommer +1
Imprints of galaxy cluster formation processes are visible in the intracluster medium and can arise in shock fronts, which are detectable via discontinuities in e.g. the gas temper…
Weak-lensing mass calibration of the Sunyaev-Zel'dovich effect using APEX-SZ galaxy clusters
A. Nagarajan, F. Pacaud, M. Sommer +16
The use of galaxy clusters as precision cosmological probes relies on an accurate determination of their masses. However, inferring the relationship between cluster mass and observ…
MERGHERS: An SZ-selected cluster survey with MeerKAT
Kenda Knowles, Andrew Baker, Kaustuv Basu +20
The MeerKAT telescope will be one of the most sensitive radio arrays in the pre-SKA era. Here we discuss a low-frequency SZ-selected cluster survey with MeerKAT, the MeerKAT Extend…
