(Monty Python and the) HoliGRALE: A Hybrid GRALE Lens Inversion Methodology Diagnostically Evaluated with Synthetic and Real Data
Derek Perera, Jori Liesenborgs, John H. Miller +4
We present HoliGRALE (Hybrid, only light included, GRAvitational LEnsing), a hybrid lens modeling extension of the freeform method GRALE. HoliGRALE incorporates physically motivate…
Shape Degeneracies: the likely culprit for the differences between lens mass models of galaxy clusters
Liliya L. R. Williams, Derek C. Perera, Jori Liesenborgs +3
Sky-projected mass distributions of galaxy clusters are widely used to constrain particle properties of dark matter, to magnify in flux and angular extent high redshift background…
DIVERSE: Disagreement-Inducing Vector Evolution for Rashomon Set Exploration
Gilles Eerlings, Brent Zoomers, Jori Liesenborgs +2
We propose DIVERSE, a framework for systematically exploring the Rashomon set of deep neural networks, the collection of models that match a reference model's accuracy while differ…
Testing Light Unaffiliated Mass Clumps in MACS 0416 on galaxy and galaxy cluster scales using JWST
Marceau Limousin, Derek Perera, Gregor Rihtarsic +2
Light unaffiliated mass clumps (LUMCs), i.e. dark matter (DM) components without any stellar counterparts, have been reported in strong lensing mass reconstructions of MACS 0416, b…
AI-Spectra: A Visual Dashboard for Model Multiplicity to Enhance Informed and Transparent Decision-Making
Gilles Eerlings, Sebe Vanbrabant, Jori Liesenborgs +3
We present an approach, AI-Spectra, to leverage model multiplicity for interactive systems. Model multiplicity means using slightly different AI models yielding equally valid outco…
Are Models of Strong Gravitational Lensing by Clusters Converging or Diverging?
Derek Perera, John H Miller, Liliya L. R. Williams +4
The increasingly large numbers of multiple images in cluster-scale gravitational lenses have allowed for tighter constraints on the mass distributions of these systems. Most lens m…
