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...

A Massive Barred Spiral Galaxy at z = 5.102 Discovered by JWST

Abstract We report M1149-BSG-z5, a barred spiral galaxy at z = 5.102, identified in the parallel field of MACS J1149+2223 with JWST and the Hubble Space Telescope. M1149-BSG-z5 is the highest-redshift barred galaxy candidate to date. Both isophote ellipse fitting and structural m...
