A massive barred spiral galaxy at z = 5.102 discovered by JWST

Xiaohan Wang, Fengwu Sun, Yoshihisa Asada +21

We report M1149-BSG-z5, a barred spiral galaxy at , identified in the parallel field of MACS J1149+2223 with JWST and HST. M1149-BSG-z5 is the highest redshift barred ga…

Mass Production of 2023 KMTNet Microlensing Planets. II: Two Planets and A Brown Dwarf

Zhixing Li, Hongyu Li, Weicheng Zang +63

To expand the homogeneous microlensing planetary sample of the Korea Microlensing Telescope Network (KMTNet), we investigate six planetary candidates identified by the AnomalyFinde…

Microlensing Events in Five Years of Photometry from the Zwicky Transient Facility

Ruocheng Zhai, Antonio C. Rodriguez, Shude Mao +5

Microlensing has a unique advantage for detecting dark objects in the Milky Way, such as free-floating planets, neutron stars, and stellar-mass black holes. Most microlensing surve…

The Optical Gravitational Lensing Experiment. Variable Baseline Microlensing Events in the Galactic Bulge

L. Wyrzykowski, A. Udalski, S. Mao +5

We present the first systematic search for microlensing events with variability in their baselines using data from the third phase of the Optical Gravitational Lensing Experiment (…

Optical Gravitational Lensing Experiment. OGLE-1999-BUL-32: the Longest Ever Microlensing Event -- Evidence for a Stellar Mass Black Hole?

Shude Mao, Martin C. Smith, P. Wozniak +5

We describe the discovery of the longest microlensing event ever observed, OGLE-1999-BUL-32, also independently identified by the MACHO collaboration as MACHO-99-BLG-22. This uniqu…

Optical Gravitational Lensing Experiment. OGLE 2000-BUL-43: A Spectacular Ongoing Parallax Microlensing Event. Difference Image Analysis

I. Soszynski, K. Zebrun, P. R. Wozniak +7

We present the photometry and theoretical models for a Galactic bulge microlensing event OGLE-2000-BUL-43. The event is very bright with I=13.54 mag, and has a very long time scale…

The Optical Gravitational Lensing Experiment. OGLE #7: Binary Microlens or a New Unusual Variable?

A. Udalski, M. Szymanski, S. Mao +5

We present the light curve of an unusual variable object, OGLE #7, detected during the OGLE search for microlensing events. After one season of being in a low, normal state, the st…
