We present a new strong-lensing and X-ray mass model of the merging galaxy cluster SPT-CLJ1150-2805 (), combining JWST NIRCam, HST, Chandra, and VLT/MUSE data to robustly…
Resolving 3 Exotic Hyperbolic-Umbilic Lensing Configurations in the "Cosmic Mantis": An Exploration of RXJ0437.1+0043 with JWST
Catherine Cerny, David J. Lagattuta, Keren Sharon +12
We present an updated strong lensing model for the galaxy cluster RXJ0437.1+0043 (z=0.285) using new JWST NIRCam imaging in four pass-bands. The cluster field notably displays at l…
Non-spherical BUFFALOs: a weak lensing view of the Frontier Field clusters and associated systematics
A. Niemiec, A. Acebron, B. Beauchesne +15
Galaxy clusters are tracers of the large scale structures of the Universe, making the time evolution of their mass function dependent on key cosmological parameters, such as the co…
A first GLIMPSE into star clusters populations across cosmic time
Adélaïde Claeyssens, Angela Adamo, Vasily Kokorev +12
We present the first sample of 222 high-redshift (z>0.5) star clusters, detected with JWST/NIRCam in 78 magnified galaxies from different galaxy cluster fields. The majority of the…
SLICE -- Combining Strong Lensing and X-ray in AC 114. Further Insights into the Merger Scenario
Marceau Limousin, Benjamin Beauchesne, Keren Sharon +14
AC114 is a historically significant galaxy cluster, being one of the first strong lensing clusters detected from the ground in the early 1990s, prior to the launch of the HST. Desp…
A Strong Gravitational Lensing Model of PSZ2 G118.46+39.32
Isaac Smith, Catherine Cerny, Keren Sharon +4
We present the first strong gravitational lensing model for the cluster PSZ2 G118.46+39.32 (z = 0.3967) using new NIRCam imaging from the Strong LensIng and Cluster Evolution (SLIC…
JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization
Hakim Atek, John Chisholm, Vasily Kokorev +44
We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…
A comprehensive separation of dark matter and baryonic mass components in galaxy clusters II: an overview of the mass distribution in Abell S1063
Benjamin Beauchesne, Benjamin Clément, Marceau Limousin +11
In the first paper of this series, we derived mass constraints on the total mass and the baryonic components of the galaxy cluster Abell S1063. The main focus was to recover stella…
A comprehensive separation of dark matter and baryonic mass components in galaxy clusters I: Mass constraints from Abell S1063
Benjamin Beauchesne, Benjamin Clément, Marceau Limousin +11
In this two-part series, we present a multi-probe mass modelling method for massive galaxy clusters, designed to disentangle the contributions of individual mass components (Dark m…
Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk
Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21
We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…
Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections

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…
Mass & Light in Galaxy Clusters: The case of Abell 370
M. Limousin, A. Niemiec, B. Beauchesne +16
Parametric strong lensing studies of galaxy clusters often display "misleading features". This is the case in the galaxy cluster Abell 370. Using strong lensing techniques, it has…
