A redshift of z=3.20 for the bright arc in eMACSJ2229.9-0808: Comment on Wagner & Falco (2026) "Hamilton's Object revisited: A challenging source redshift of a strong lensing configuration"

Ian Smail, Johan Richard, Harald Ebeling +1

We re-analyse near-infrared and optical spectroscopy from the Subaru, Gemini, and Keck telescopes of the bright gravitational arc seen in the z=0.62 X-ray cluster eMACSJ2229.9-0808…

Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections

Catherine Cerny, Guillaume Mahler, Keren Sharon +24

We leverage JWST's superb resolution to derive strong lensing mass maps of 14 clusters, spanning a redshift range of and a mass range of $M_{500}\sim2-12 \times…

SLICE: SPT-CL J0546-5345 -- A prominent strong-lensing cluster at

Joseph F. V. Allingham, Adi Zitrin, Miriam Golubchik +15

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…

The Kaleidoscope Survey: Strong Gravitational Lensing in Galaxy Clusters with Radial Arcs

Catherine Cerny, Mathilde Jauzac, David Lagattuta +5

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 c…

The fifth data release of the Kilo Degree Survey: Multi-epoch optical/NIR imaging covering wide and legacy-calibration fields

Angus H. Wright, Konrad Kuijken, Hendrik Hildebrandt +51

We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational lens…
