Lensing in the Blue. III. Weak-lensing Shape Catalogs of 30 Merging Galaxy Clusters

Abstract 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 2023 April–May. SuperBIT is a first-of-its-kind balloon-borne imaging telescope that achiev...

Shear Mapping in Python (SMPy): Modular, Extensible, and Accessible Dark Matter Mapping

SMPy makes convergence maps from weak lensing galaxy shear catalogs with Kaiser-Squires inversion, KS+ and aperture mass, together with signal-to-noise maps, celestial and pixel coordinates, and plotting.
