Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
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…
JWST & the Waz Arc I: Spatially Resolving the Physical Conditions within a Post-Starburst Galaxy at Redshift 5 with NIRSpec IFS
Taylor A. Hutchison, Gourav Khullar, Jane R. Rigby +22
We present NIRSpec/IFS observations of a rest-frame UV-bright, massive ( M, ) galaxy highly magnified by gravitational-lensing observed just…
Tracing Structure: Shape and Centroid Deviations in 39 Strong Lensing Clusters as a Test of Cluster Formation Predictions
Raven Gassis, Matthew B. Bayliss, Keren Sharon +10
Strong lensing galaxy clusters provide a unique and powerful way to test simulation-derived structure predictions that follow from Cold Dark Matter (CDM) cosmology. Specific…
The Chandra Strong Lens Sample: Measuring the Dynamical States and Relaxation Fraction of a Sample of 28 Strong Lensing Selected Galaxy Clusters
Raven Gassis, Matthew B. Bayliss, Michael McDonald +10
We present the results of our dynamical state proxy measurements performed on 28 strong lensing galaxy clusters from the Sloan Giant Arcs Survey (SGAS). Using Chandra ACIS-I/S X-ra…
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…
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…
The z=1.03 Merging Cluster SPT-CL J0356-5337: New Strong Lensing Analysis with HST and MUSE
Grace Smith, Guillaume Mahler, Kate Napier +8
We present a strong lensing analysis and reconstruct the mass distribution of SPT-CL J0356-5337, a galaxy cluster at redshift z = 1.034. Our model supersedes previous models by mak…
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…
Tiny galaxies and dark substructures: exploring the "dark" subhaloes in TNG50
Jessica E. Doppel, Mathilde Jauzac, David J. Lagattuta +2
Dark matter haloes and subhaloes that host no luminous counterpart are predicted within our current understanding of galaxy formation within a CDM paradigm. Observational tests,…
Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections
