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...

You Shall Not Pass (Without Modeling): High-resolution Analysis of KMT-2019-BLG-0253 using MORIA

Abstract We present the Microlensing Object high-Resolution Imaging Analysis pipeline, or MORIA . This is an automated procedure to reduce high-resolution Hubble Space Telescope (HST) images of microlensing targets, build empirical point-spread function (PSF) models from the data...
