SLICE: SPT-CL J0546-5345—A Prominent Strong-lensing Cluster at <i>z</i> = 1.07 Open
Massive galaxy clusters act as prominent strong lenses. Due to a combination of observational biases, cluster evolution, and lensing efficiency, most of the known cluster lenses lie typically at z l ∼ 0.2–0.7, with only a few prominent exa…

The Kaleidoscope survey: strong gravitational lensing in galaxy clusters with radial arcs Open
We measure the dark matter density profiles of six galaxy clusters: A383, MS 2137–23, MACS J0326.8−0043, MACS J1427.6–2521, MACS J0417.5−1154, and MACS J0949.8+1708. Each cluster contains at least one radial arc, a unique physical feature …
Molecular gas in cool-core brightest cluster galaxies at <i>z</i> ≃ 0.4 Open
The brightest cluster galaxies (BCGs) of today are passive and very massive galaxies at the center of their clusters. They still accrete mass by swallowing companions and flows of cold gas, processes which are regulated by radio-mode activ…
