Four binary microlenses with directly measured masses

Cheongho Han, Andrzej Udalski, Chung-Uk Lee +58

We investigated binary lens events from the 2022-2024 microlensing surveys, aiming to identify events suitable for lens mass measurements. We focused on two key light curve feature…

Towards sub-milliarcsecond astrometric precision using seeing-limited imaging

Noam Segev, Eran O. Ofek, Yossi Shvartzvald +21

The Earth's atmospheric turbulence degrades the precision of ground-based astrometry. Here, we discuss these limitations and propose that, with proper treatment of systematics and…

LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs +20

Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often le…

ET White Paper: To Find the First Earth 2.0

Jian Ge, Hui Zhang, Weicheng Zang +163

We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…

Spitzer + VLTI-GRAVITY Measure the Lens Mass of a Nearby Microlensing Event

Weicheng Zang, Subo Dong, Andrew Gould +24

We report the lens mass and distance measurements of the nearby microlensing event TCP J05074264+2447555. We measure the microlens parallax vector using Spitzer and gro…
