Mode Switching in Two Blue Large-amplitude Pulsators Observed by OGLE, KMTNet, and DREAMS

Abstract Blue large-amplitude pulsators (BLAPs) are rare, hot, short-period pulsating stars whose rapid oscillations provide a unique probe of stellar interiors and atmospheres. In this paper, we study two short-period BLAPs in the Galactic bulge, Optical Gravitational Lensing Ex...

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...
