The BUFFALO Survey : The Subhalo Mass Function for Abell 2744 with Strong+Weak Gravitational Lensing
Nency R. Patel, Mathilde Jauzac, Anna Niemiec +16
We present a combined strong and weak gravitational lensing mass model of the massive merging galaxy cluster Abell 2744 (z = 0.308). The mass reconstruction combines strong-lensing…
Sub-kiloparsec Test of the Kennicutt-Schmidt Relation in a Strongly Lensed Dusty Star-Forming Galaxy at z~2.78
C. Cornil-Baïotto, J. Molina, G. Mahler +9
[abridged] Star formation is a key process driving galaxy evolution, but understanding how it proceeds within the interstellar medium (ISM) requires resolving cold molecular gas an…
SLICE: Unveiling the Multi-Component Merging Core of SPT-CLJ1150-2805 Through Strong-Lensing Mass Modelling
James R. Betts, Benjamin Beauchesne, Mathilde Jauzac +16
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…
SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…
Intracluster light in the infall region of simulated protoclusters of galaxies
S. V. Werner, M. Jauzac, M. Montes +4
Intracluster light (ICL) is a diffuse stellar component in galaxy clusters, made of stars following the potential of the cluster. Despite its potential to unveil the accretion hist…
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…
Imprints of Mass Accretion History on Galaxy Cluster Morphology
Kabelo Tsiane, Camille Avestruz, Elena Rasia +6
Variations in dynamical states of galaxy clusters can introduce biases and scatter in observable-mass relations. The dynamical state of a cluster is an emergent feature of its mass…
LEGGOS I: The JWST LEGGOS Survey -- LEnsing and Galaxy Growth: Observing Substructures -- Unpacks the Nature of Clumpy Star Formation and Quenching in Gravitationally Lensed Galaxies beyond Cosmic Noon
Gourav Khullar, Michael Florian, Matthew B. Bayliss +34
We present first results from the JWST LEGGOS Survey (LEnsing and Galaxy Growth: Observing Substructures), aimed at studying the physics of clumpy star formation and quenching in e…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey
L. E. Bleem, M. Klein, K. Kornoelje +148
We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resol…
LEGGOS II: A Strong Lens Model and Source-Plane Projection of the Clumpy Star-Forming Galaxy SGASJ111020.0+645950.8 at z=2.48
Pedram Abedi, Keren Sharon, Taylor A. Hutchison +18
Strong gravitational lensing by galaxy clusters combined with the resolution of JWST enables studies of star formation on ~10-100 pc scales in galaxies at z~2-4. As part of the LEn…
LEGGOS III: Mapping Star Formation and Dust in Gravitationally Lensed Galaxies with , a UMAP and Clustering Framework
Alex Ross, Gourav Khullar, Taylor Hutchison +10
Strong gravitational lensing combined with JWST's spatio-spectral resolution enables resolved studies of star-forming regions in 2-4 galaxies, but identifying and character…
COOL-LAMPS IX: A Rare Duo of Quasars Each Lensed by a Single Massive Galaxy Cluster
Erik Solhaug, Michael D. Gladders, Andi M. Kisare +20
Wide-separation lensed quasars (WSLQs) are rare systems that arise from the chance alignment of two objects: a galaxy cluster and a background quasar. After two decades, only seven…
SN 2022riv in RX J2129: Discovery, Spectroscopic Classification, and Microlensing of a Strongly Lensed Type Ia Supernova from JWST and HST Observations
Birendra Dhanasingham, Patrick L. Kelly, Wenlei Chen +27
The multiply imaged SN 2022riv was discovered through a search of galaxy cluster fields as part of a Hubble Space Telescope (HST) SNAP program to find highly magnified stars. The s…
A Kiloparsec-Scale Stellar Cavity in the Center of Abell402-BCG May be Caused by Dynamic Interactions with an Ultramassive Black Hole
Michael McDonald, Gourav Khullar, David Lagattuta +18
We present new observations from JWST NIRCam that reveal a striking kpc-wide cavity in the stellar distribution of the central galaxy in the cluster Abell402. Supporting data from…
An ultra-high-resolution map of (dark) matter
Diana Scognamiglio, Gavin Leroy, David Harvey +38
Ordinary matter-including particles such as protons and neutrons-accounts for only about one sixth of all matter in the Universe. The rest is dark matter, which does not emit or ab…
