Lensing in the Blue IV: The First Weak Gravitational Lensing Maps from the Stratosphere

The Super-Pressure Balloon-borne Imaging Telescope (SuperBIT) completed its science flight in April 2023, obtaining imaging data for 30 galaxy clusters. In this work, we present the first weak-lensing convergence maps from these observations, using six clusters selected from the 30 targets. We construct background-gala...

Model independent lensing sub-structure detection with multiply-imaged star clusters constellations

A broad class of dark matter (DM) models predicts the existence of sub-structures residing in DM haloes on sub-resolvable angular scales. Techniques to extract such a generic feature from diffraction-limited observations are lacking. In this work, we propose a model-independent'super-resolving'method applicable to stro...
