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…
Euclid. A two-point correlation approach to diagnosing star-related systematics in the Euclid spectroscopic survey
Euclid Collaboration, I. Risso, B. R. Granett +298
The Euclid spectroscopic survey will measure galaxy clustering with unprecedented precision, requiring stringent control of observational and instrumental systematics. Star-related…
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…
Lensing in the Blue III: Weak Lensing Shape Catalogs of 30 Merging Galaxy Clusters
Sayan Saha, Jacqueline E. McCleary, Spencer W. Everett +38
We present the weak gravitational lensing dataset from the Super-pressure Balloon-Borne Imaging Telescope (SuperBIT), which imaged 30 galaxy clusters during its 45 night flight in…
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 shot in the dark: searching for dark substructures in the RX J0437+00 galaxy cluster
David J. Lagattuta, Mathilde Jauzac, Jessica E. Doppel +2
Obtaining a census of dark matter structures at low mass () can provide strong constraints on the nature of dark matter, though identifying such structures remai…
